Maintenance is a part of RC, like it or not. That said, Mugen or XRay, hands down IMO. I drove the MBX6 last summer. The initial build was stellar. The durability second to none. I just felt it didn't fit how I like to drive. So this year, I'm gonna run the Hot Bodies D8/D8T. I've run the T for a few months now, and aside from basic maintenance, it has been rock solid and an absolute blast to drive. I'll be running the bug for the first time this w/end.
