I guess to me it depends on the form. Only using Mugen makes sense to me, because it's the strongest. Sure, it might be overkill to take out mooks with it, but if you were fighting evil monsters, why would you want to go easier on the weaker ones? If the suit is completely OP, then it makes complete, 100% sense to me to continue using it over the base suit.

I do agree about the drawbacks though - it makes suits more interesting when the final forms have some. For example, Dead Heat. Sure, Drive gets more upgrades, but it ends up becoming Mach's final form, and he doesn't use it a lot because of the drawback. But he eventually manages to work around the drawback and use it to his advantage. From what I remember, it still takes a toll on his, but it's a lot easier to control. Using suits like this raise the stakes and are more interesting because of it.

So I definitely agree that final forms with drawbacks are more interesting, but they don't always end up like that. If they're using something like Mugen that has no drawbacks, it really doesn't make sense (to me) to not use it.
