I was also concerned about reviews that slated the 3D on the Samsungs seeing as i'm a bit of a fan boy of their tvs
Tried loads of different sets in the shops and couldnt see any noticeable difference in my price range if i'm honest, tried the 3D on both Blueray and my Xbox and it's spot on for me? 2D to 3D conversion also works great on MW3 for me and Emmerdale for the missus lol!
I try to take the reviews with a pinch of salt as most get far too indepth for what at the end of the day is a posh telly, i'm never going to run a 3D test disc and measure for image crosstalk nor am i going to measure my gaming screen response time down to the last millisecond...
My advice, get the set that impresses YOU the most in your price range and dont get too hung up on 'pro' reviews, one mans meat and all that...
