I don't understand why so many people admit they haven't tried 3D, then go on to claim it's rubbish 🙂
How can you know? From looking at a TV in a shop? I think a lot of in-store displays are set-up with the 3D effect set to max, the same way the picture modes are often set to Vivid. It's just to be eye-catching. But very few people judge a TVs picture quality on an in-store demo with silly settings, so why judge its 3D that way? Wait 'til you see it on a decent set, well set-up, with decent content. Then judge.
I wasn't sure about 3D, but now I use it a lot. I think it's great. IMO, it's not a gimmick. I use it for a variety of things, but mainly watching sport and gaming. Watching the Masters golf in 3D was absolutely fantastic. It showed the undulations of the course in a way that I've never seen with 2D.
I wouldn't say I prefer 3D over 2D, it doesn't suit everything. But when the content is suitable, it's a whole new AV experience, and I'm all for those!
