Yes mate,keep getting Plasma suggested to me but thought LCD was better?
Both have their own benefits. For a great all round solution you can't go far wrong with a good LCD from Sony or perhaps Samsung. As a general rule though plasma will offer deeper black levels, and more fluid 'real' motion. There's nothing wrong with the motion on a good LCD, but a good plasma will almost always have the edge in that regard. Black levels are better on plasma too, and there's no chance of any uneven backlighting or backlight bleed.
The downsides of plasma are that they're heavier, consume more energy, and can possibly suffer from mild temporary image retention or even burn, if you leave a static high contrast image on the screen for hours and hours.
I went for plasma just recently and I love it. I think the 1080p/24 motion is smoother than any LCD I've seen displaying the same material. So smooth that action sometimes appears to actually be in the room with you. Saying that, you won't be disappointed with a good LCD so it really comes down to what you want. If you're a serious movie AV buff, then plasma could be better due to the better blacks and motion. If you're a casual TV watcher then LCD is probably a better bet. If you play lots of games then LCD makes more sense due to zero chance of retention. Saying that, I had an epic gaming sesssion on my plasma the other week and there was no hint of any retention at all.
Only you can decide what's best for you TBH.
One other thing to consider is that plasma will have a lovely glass screen, which I personally prefer to the typical membrane look of an LCD. Plasmas look much better as a piece of furniture because of this IMO.
