I had a LED, and a team mate a LCD.
Both got a good soaking at Elsham last year.
Both stopped dead during the last game.
Bugger......
But mine dried out and worked fine, His dried out and didnt! He needed a new board from WDP.
Can not say that the LED is better than a LCD, just mine worked fine. Also got to say the service from WDP was outstanding.
Hope that helps....
