I've had little to no problems with my LST, so I would have to counter balance the above post.

If you go with a LST you'll be getting a truck quite a bit larger than your current truck. I'm not sure if you want that or not but to me that was certainly an advantage. Something different.

I won't go directly into the specific difference between these two trucks as I'm sure you already know by the countless posts everything there is to know about each in terms of features, specs, top speeds and more. At the time I bought my LST I had not seen a Revo drive yet except in the videos so I was going purely by the videos released by each corporation in which the Revo was portrayed as more of a Racer to me. I know the LST was the only truck actually filmed on a track but the low profile tires of the Revo to the smaller scale ultimately made me go for something larger, hence my LST. And I can't complain, in fact I'm going out to drive it now.
