Well I really can not say much for either , I don't have them or run them
the diff / gear motor argument will go on forever . IMHO , wedico could've put a little more thought into the drive train . Leibherr model's 2plus2 seems to be well thought out . Yea I could just use gear motors /wheel in my models and make life easier
. But , I love the challenge to get as close to real as possible and function well also . You should do well digging with the little bucket
. You may still need the ripper for the occasional rock .
