I do think Left 4 Dead is awesome, but then again, that's not an exclusive either (PC).
So yes, I MUCH prefer Killzone 2, Resistance 1 & 2(meh), Infamous, MGS4, LBP, and Uncharted 1 & (hopefully) 2 to all the games you mentioned.
Yes, I like the PS3 controller better. Just personal preference on that one. Not that I think the 360 controller is garbage, it's fine, and I like that I can plug it into my PC to play some games.
I find the Xbox 360 interface clumsy and I don't like seeing advertisements every time I start it up so...
But wait! You can play dress up with your avatar! That's super awesome!!!!!!!!!! I'll take custom backgrounds instead.
And since you've only finished one PS3 game makes me wonder if you've given any PS3 game an honest chance. No doubt since you're gonna buy Uncharted 2 based just on HYPE you won't finish that one either.
I know it looks like I'm bashing the 360 but I'm not. I think that console wars are for 13 year old bedwetters. The 360 is great, I just prefer the PS3. Just like you prefer the 360. No big deal. There's enough room in my entertainment center for both and have enjoyed both a great deal.
...and I'm pretty sure can stream Netflix on your PS3 if you're willing to go an extra step (How to Stream Netflix Movies to Your PlayStation 3 - Gadgetwise Blog - NYTimes.com)
