My Opinion on LCD / LED / Plasma (base on my eye):

Plasma

Pros

• Better in motion, you hardly seen any ghost / blur issue when object move.
  
• Better black compare with LCD.
  Cons
  
• If you seen closely, you will notice the way it draw line a bit like old fashion CRT TV.
  
• Not as sharp and details compare with LCD / LED.
  
• Dislike the glossy surface (most plasma) which will impact on viewing.
  
• Image Burn-in issue.
  
• Old tech which I believe soon will be obsolete.
  

LCD

Pros

• Sharpen in details.
  
• Power Saving
  
• Brighter.
  Cons
  
• Motion blur / ghost effect occur compare with plasma, high end series with higher Hz like 120hz or 200hz reduce more on ghost effect. 24P helping on it as well.
  
• Angle view not as wide compare with Plasma.
  
• Not ready true black as Plasma or LED. (After some fine tune, it looks nice)
  

LED - Backlight (Edge)

Pros

• True Black.
  
• Vivid color (sometimes I find it over vivid which became un-natural).
  Cons
  
• More problematic on motion issue, it actually generate more ghost effect in low end model compare with LCD.
  
• Expensive.
  

At the moment, I still suggest on LCD unless money is not your concern, then get a high end series of LED (with higher Hz for better in motion).

Plasma I won't get as it got burn-in issue, obsolete soon tech & not appealing me.
