I have heard of ROH, I'm sure it's filled with a lot of talented wrestlers. The WWE now definitely isn't what it used to be, but then again, all the guys you listed, chances are you'll only have one of them in a lifetime. They all had their own charisma, brand of wrestling that separated them from everyone else. I can see where you're coming from in regards to "roiled out pretty boys" (e.g. see Batista, possibly Cena, etc. etc.)
What you will find nowadays, despite the presence of said roiled out pretty boys, are guys like Rollins (or Tyler Black), Ambrose (or Jon Moxley) and Reigns, they have been working really well lately, are quite over with the crowd. The match they had on with Evolution, was exciting (despite Batista's limited personality and Orton's limited personality AND move set).
Cesaro (Claudio Castagnoli) is another guy well over with the crowd, also a former ROH wrestler. Same can be said about Daniel Bryan (or Bryan Danielson) who is currently wearing the WWE and WHC belts at the moment. There is a new wave of PROPER wrestlers coming through now.
As for the Miz... that was 3 years ago. We try not to talk about that incident.
Point being, WWE today isn't as good as it was some 15 years ago. Probably never will be. But I can guarantee that it is (and is getting) better than it was 1.5-4 years ago.
Even if you don't watch Raw or Smackdown, at least give NXT a viewing - there's always a good showing or 2 there.
