I switched from a MBX-6 electric conversion to the EB and the Tekno has been way more durable. It's very nice to have a car that the arms fit either side which means I don't have to have as many spares. Plus it shares parts with my SCT and now the NB. I've yet to break anything on my EB but I did break several front/rear arms and bent hinge pins on the Mugen. I was also replacing the steering tierod ends often because the wheels rubbed at full lock and it still didn't turn enough. The Tekno also has no slop and is much easier to work on.

I agree with everything that Kevin mentioned before about the Mugen handling the rough better but it's because it weighs so much more. Someone asked me to compare the two when I first got the Tekno and I told them the Mugen was more like a Cadillac, easier to drive but slower, and the Tekno was a Porsche, same equipment was way faster (much lighter), more nimble, and it wants you to drive faster.

I love my Tekno stuff. I don't dread working on them because all I every have to do is clean it.
