I've been working in CC's video dept for about two years.
I'd buy a Plasma. I'd say CRT, because all I really need is a 34", but the only quality CRT out there are Sony's 970s. I already regret selling my 26" panny CRT now that i've got a 360. XBR2 lcds were also a close one for me, but after running Gears of War through all our TVs, I'd still get a Plasma, not just because of price. I'll list why, and I'm sure someone can list why they'd get an LCD and sound just as convincing. Plus these are based on what I use it for. If you break it down to how you're gonna use it and your preferences, it'll help when you decide to get your tv, instead of having people make recommendations.
-Black levels are as close to a CRT as I can get. XBR2/3 look pretty stunning, but beside even a Panny plasma, the blacks can't be beat. Fujitsu and Pioneer have even better sets, but the Pannys go for less than the xbr2 in comparable sizes.
-Lower resolution(depending on size), I don't watch much tv. If I need to use some sort of video, it's with games(40%), movies(30%), SD(20%), HD(10%). Considering that 50% of what I'm watching isn't in HD, the higher resolution sets are only gonna hurt my picture(yes, even with the better upconverting dvd players/video cards with powerDVD. It can be bearable, but not to par with what I get on HD). However, when I do want to watch 24, or Smallville in HD, or get some GoW or R6 on, I can still do so with great quality.
-Plasmas can be adjusted to avoid black crush, but still look deep. On some LCDs, making similar adjustments just wash out the image and suck out all the life.
-Very little problems with off axis viewing. I thought the XBR2 didn't have this problem, but it does. I was comparing it with the V2500 today, and was telling myself how poor the V2500's color was while standing in front of the XBR2. Then I walked the 6 foot distance to the V2500, and saw the XBR2 did the same thing.
and yeah. I hooked GoW to all our TVs. I think our Samsung DLPs and our Panny plasmas looked best. XBR2 was also good in detail, but the colors just weren't eye popping, almost flat and monotone looking. It looked way too neutral. It offered more detail than the Panasonic, but when I think about it, color strikes me first before details. I'm gonna notice someone's flesh tone is off from normal before I notice that he's got any more pimples.
I personally use the internet more than anything, so to me a TV is almost a waste. I used to use my now sold 50" dlp as a giant computer monitor, more than for video. I think ill be fine with my 19" lcd and some nice future headphones
