Trugs pros
-Far better on rutty/bumpy tracks
-less prone to traction rolls
-tyres last longer
-bigger

Negatives
-usually more expensive
-break easier (longer arms ect)
-tyres are expensive
-class is still taking off
-parts can be more expensive


Buggy pros
-loads to choose from
-always a big turn out on race day
-easy to work on
-cheaper parts
-a bit more challenging
-faster on smooth tracks
-usually take a battering better than truggies and are more forgiving

Negatives
-a bit more challenging
-inferior on bumpy tracks
-tyres don't last as long
-tyres erode the tracks surface faster
-more fiddly to setup


Both are fun, pending on what condition the track is in Sunday morning I bring both bug and trug along, although I only race 1 class on the day.
