Alot of people down the ASV style tracks because they are what they are....that is a rubber on rubber system, introduce some 11/4" crushed stone or very sharp rock, some mud packed in the track system and WHAM, chunks gallore! I personally think it is a good system, has a bit of suspension (via tor-flex axels), puts lots of track surface on the ground, and provides low ground pressure. It is a royal PIA to clear the tracks completely of mud though, which makes for an interesting result after sitting for the night in 10 degree weather. The ASV system is not for everyone, it requires thourough cleaning everyday and the adjustment procedure is...well... a procedure to put it nicely, although I have 600hrs on my 287B and have only had to adjust em' once. The other companies track systems are basically a modified mini excavator undercarriage and WILL take more abuse but won't give you the ride quality or the low ground pressure.
