I said that against CM Slowbo he isn't staying in(and Haze Milotic too. I forgot to mention LOtic)
Let's compare both Raikou and Entei against some of the threats on the UU metagame:
PS: LOOOOOONG POST
Rhyperior: No one stays in. Raikou obviously has to switch out, so does Entei. IF you use Lava Plume on the exact switch you have 30% chance of burning it(and cutting
his usefulness a lot). Raikou won't even hit it.
Azumarill/Feraligatr: Again, Lava Plume can burn on the switch. But Raikou easily beats those ones.
Bulky Waters: Lol Raikou obviously. Entei only has a chance IF THEY HAVE A TANK SET(Caps Lock on that because i think both of you didn't understand that part). Any other set from them and Entei loses. Badly. Poor Entei.
Bulky Grounds: Entei obviously even though both are hit for SE.
Venusaur: sets up on Raikou(if it's a SD set). Special sets and Raikou can set up. Entei just beat this regardless of the set.
Swellow: Raikou OHKO it. Entei needs 2 Lava Plumes. But can survive some Facades better than Raikou.
Aggron: Both can beat this. EQ does a number on Raikou and Head Smash is OUCH to Entei (actually one of the only things that can OHKO a full health Entei with physical hits, the other being... CB Stone Eges from Rampardos and Rhyperior... ans CB Waterfall from Azumarill). Again, 30% chance of crippling it for the rest of the match, but don't count on it.
Chansey: both lols at Chansey. Entei can take 5 Seismic Tosses with Leftovers. Raikou hits harder. But Entei can burn it so it ends doing a little more damage(believe me, many people let Entei set up his 6 CM... dunno why)
Arcanine: Raikou can beat it easily. Entei can beat through PP stalling(Flash Fire versions) or CM Lava Plumes(Intimidate without Roar). Roar means annoyance to Entei.
PS: Here 031 said about Morning Sun. Morning Sun has only 8 PP, and Arcanines without Roar are an excuse for Entei to set up CM(Intimidate again). If you stay on Flash Fire versions you can PP stall it... but at the risk of sleeping while the adversary predicts it and send something to scare it off.
Blaziken: SD versions are more rare(don't say it isn't because it is). Raikou can beat it more easily, but Entei handles it well(versions without SD)and uses Blaziken as an excuse to set up more CMs than Raikou(which will just force it out). Scarf versions are a problem to Raikou though, and are lol to Entei.
Alakazam: If it has Encore, both are Encored and forced to switch. Without Encore, it just hits both hard or Trick something to it. No advantage here.
Froslass: both are going to be Taunted and Destiny Bonded. Entei has SE hits though(and blablabla burn shit)
Mismagius:here 031ap said about Mismagius on the sweeping side of the thing. Which isn't the case of this discuss.
Both can handle Mismagius. That's it.
Rotom: Entei. Raikou can use Rotom as an excuse to set up though. If both are Tricked...
Clefable: Both can handle it. CM versions are annoying to both(but Entei resists Ice Beam, and Raikou resists Thunderbolt). Both can be Encored. Entei can take Facades better. Raikou deals more damage.
Tangrowth: isn't going to stay in against both. Especially Entei.
Honchrow: Brave bird is resisted by Raikou. Against Entei Brave Bird is suicidal. But a damaged poke is better than a dead one, so Raikou wins.
Altaria: DD versions are a pain for both. But Raikou hits for neutral so it wins. Entei loses here again.
Houndoom: Raikou. Entei is set up on. Bring your wall or else...
Ambipom: Entei. Raikou can't stay against repeated Returns to set up his CM. Entei can.
Drapion: draw. Raikou outspeeds, Entei takes the hits like nothing.
Dugtrio: means a dead Raikou. Entei can survive his CB Earthquakes with plenty of health left. And can hit Dugtrio. But won't KO without a CM or two.
Registeel: Most are going to Explode against Entei. Takes less than 50% from his Explosion. Against Raikou they can EQ then Explode for the KO. So with Raikou you need to predict correctly while with Entei you can set up wuth less worries.
Hariyama: Entei uses it as an excuse for set up(ones without Whirlwind... not many of them unfortunately). Raikou is on the same boat. Guts ones means pain for both.
Any poke used on rain dance teams: Raikou. No more comments here.
Sceptile: Entei. No more comments here.
Scyther: wow, suddenly Raikou is slower... maybe has to deal with a SD Bug Bite or a U-Turn. U-Turn is soft on Entei. can take a SD Aerial Ace better than Raikou can take the SD Bug Bite. Baton Pass to someone? Ugh... both won't like that...
Nidoking: ENTEI. Though both are likely to lose. Entei at least blablabla luck.
Spiritomb: lol for both.
Steelix: Entei. Entei. Entei.
Weezing: both. Entei can shrug Will-o-Wisp(with Rest that doen't matter much)
Umbreon: both. As Lemmiwinks MkII said, it's easier for Entei since it can burn them on a Curse set and the burn can't be reflected back. Other sets are equal for both.
Torterra: ENTEI.
Moltres: RAIKOU. But Entei can use it as an excuse to set up on. But can be PP stalled just like Entei can PP stall Moltres.
Toxicroak: Entei. Raikou is faster and can beat it too though.
Uxie/Mesprit: Both.
Hitmons: both. But i dunno if Raikou can take repeated Close Combats. There's Mach Punch to hit both before they sleep.
So there you go. Raikou beats some key pokes Entei can't. Especially some more used threats(waters?Check. Swellow and Honchrow? Check). He can take more threatening pokes with more ease than Entei, who struggles against most of them.
Entei can try and beat/cripple most of his counters unlike Raikou. And can take a large portion of the less used UU pokes(and some of the most used too). So he's scared off more often, but it can push his luck(PS: switchins mostly) and help his teamates.
If you don't agree with something i said here, then post what and why you don't agree.
I(MY OPINION) still prefer to use Entei. Who's better? Dunno. And i never said Entei was better lol, i said that i prefer Entei PERSONALLY.
PS: I HATE being dislogged everytime... damn lol
