The Dominator is the best Ofna MT IMO. Very good racer and basher all around good truck.
The best OFNA MT certainly isn't saying all that much.

I don't think OFNA's are BAD MT's, but it is a pretty tiny niche in their product line, & you won't see a lot of aftermarket support for ANY of their MTs. From what I've seen/read, the Titan is woefully underpowered, the Twin Titan is a hoot, but $$$ & still not that quick, and I dunno much about the Dominator other than it looks exactly like a 4-shock T-Maxx without any rotary start option . It says it has "Torsen-style" diffs, which sound nice, but I've heard OFNAs Torsen-esque diffs are not all that rugged in buggys, so I'd think MTs would strain them even more. It's also $500.
IMO, OFNA seriously needs a new, state-of-the-art truck, as EVERY other mfg. is leaping past them. Back to your question, "are they good/rudgged?".....can't really say, but I do know that it's gonna be a lot harder to find replacement parts/upgrades than with almost any other brand.
