I don't have a clear favourite (not in terms of quality anyway), so I'll just give a mention to everyone I have something to say about, or care enough to say something, good or bad.
Chris Benoit - quite possibly the best pure wrestler in the world today, Benoit's had his current title reign coming a long, long time. I'm hoping for what's going to be a very lengthy reign indeed...however, he does need to work on his mic skills. As a face champion, I don't think he could afford to split the spotlight with a manager...for a heel, it's obviously different (heels don't need to be the hero, battling alone against impossible odds), so he's going to have to work on that part himself....in the ring, however, he's virtually perfect.
Chris Jericho - The best all round talent on RAW, Chris Jericho needs to get pushed back to the main event. Great wrestler, great mic worker, great look...it's amazing to think that a guy who is, quite frankly, the total package, is being booked in the midcard. It's sad...it really is....I'm just glad they're giving him good air time now.
Edge - I would have given him a lot more dark matches before bringing him back. From his return match, he's rusty as hell. Putting him in a team with Benoit isn't bad though, since it'll allow Benoit to cover his mistakes. However, I'm worried it might draw the spotlight away from Benoit.
Eugine (Nick Dinsmore) - I was afraid I'd hate this gimmick...but it's actually very funny. He plays it in a way that, to me, seems less like it's making fun of the character's condition, and one that leaves you more going "aww..." Didn't get to see his first match, so I don't know how they're letting him perform. If he's allowed to do his thing, he should be awesome.
Goldberg - Na na....na na na na....Hey hey hey....Goodbye...
Lance Storm - Someone remind me, why is Lance Storm working Heat? Why oh why did they drop his singles push, which was going pretty well? Why on earth is one of the best technicians in the company not on tv? DEAR GOD WHY!?
Mark Henry - Na na...na na...you get the picture.
Matt Hardy - There aren't words in the english language (or french or spannish languages) to describe how happy I am to see them using Matt Hardy again. I just hope to god they don't have him carry Kain, only to get squashed...I'm also worried he might go back to being his old generic self, without a chance to have a character, now that he's not a heel. With his Mattitude angle, he was awesome...I'm worried they're gonna drop that.
Ric Flair - just to continue from the other thread, yes, Ric shouldn't be wrestling anymore. He's only going through the motions now, no matter how hard he works, and should be strictly a manager (he's still awesome on the mic). He's still got a place in the company though...perhaps as a trainer or road agent in later years? The sheer depth of knowledge Ric Flair could give to other wrestlers is beyond belief.
Shawn Michaels - needs to stop hogging the spotlight, and realise his era came and went. This is the era of Benoit, and he needs to realise that.
Shelton Benjamin - give him the IC title, and I'll be a happy little Sera-chan.
Big Show - works hard in the ring, but will NEVER be a good worker...we all know that. However, I'm pleased to see they're finally using him as the monster he was built to be. He's more a storyline character than an in ring character, but I'm interested to see where things are going with him.
Bradshaw - Get...him...off....my...telivion...now. Worst....wrestler...in...company...right...now.
Eddie Guererro - the current god of Smackdown, and the best worker in the world at the moment.
John Cena - I'm still liking Cena...however, there seems to be a distinct possibility he's more over than anyone else in the company right now, short of Mick Foley

In fact, I'd give him even odds of getting louder pops than Eddie right now...which isn't something I want to see. As much as I like Cena, I want Eddie to get his dues as champion first, as he's had it coming just as much as Benoit.
Kurt Angle - I hate him as GM, because they don't let him add lib....He's medically cleared to wrestle by all accounts, so I would rather see him back in the ring. I find the wheelchair angle it pretty bad taste too...especially the comment about his wife on the last episode of Smackdown...there's a boundary where shock value should stop
Paul London - another guy who I stand amazed to see is not given more tv time...
Nobody else really gives me anything to think about right now...
And Krow, thank you for the pic

It shall join the others in the temple of Jericho
