Picture quality of plasma is brighter, better color, better blacks than LCD.
But LCD pictures can look quite good; we’re not talking huge differences.

Sharpness is the same for equivalent pixel counts. Some newer LCDs have 1080 x 1920 resolution, most plasmas still in the 768 x 1024 range.

Plasma is heavier and uses more power than flat panel LCD.

There are reports that plasmas are not as reliable or they don't last as long, but that is no longer true with the latest models. (Both LCD and plasmas have 60,00hr expected lifetime.) Plasma phosphors dim slowly over time (but not as fast as CRT phosphors); but direct view LCDs use flourescent lamps which also dim and eventually burn out (some are replaceable). Projection LCD sets have bulbs of limited life, but are replaceable and the lifetime is a few thousand hours of viewing.

Plasmas are subject to burn-in. A stationary image left on the screen for a long time could produce a permanent ghost image. The most risk is when viewing a lot of 4:3 ratio pictures (non-HD), which are displayed with vertical dark areas on the left and right to fill in the wide screen. Newer plasma designs have minimized this problem and here are ways to avoid it: many sets have a "stretch" mode which widens the picture to fill the whole screen, or will use gray bars instead of black bars. Burn-in also be a problem with extended playing of video games if there is a background image that remains stationary.

Plasmas come in larger sizes, although large flat panel LCDs are coming out, but they are expensive. LCD projectors can be 70".

LCD contrast and brightness can be reduced when viewing from off-center (both flat and projector, but sets will vary). At present, plasmas have very reflective front surfaces which could be a problem in room with lamps and windows that can be reflected by the screen. LCDs look better in bright environments, while plasmas look better in darker rooms.

LCD until second or third generation Plasma comes out. Plasma TVs loose about 50% of brightness in less than 5yrs of use in consumer testing labs. Unless you like to replace TVs every 5 years.
