I've had it turned on for ages, and I've never seen any problems. I'm running an older dual core AMD, I actually need it to get some things running at full speed. As I recall, Donkey Kong has issues for me with multithreading off. If it's on by default, the devs must be pretty confident of it as well.

It's worth trying, but I wouldn't expect too much. HT is somewhat useful for reclaiming cycles from apps that leave the CPU idle a lot, but for code that is fairly tightly written, it doesn't do very much. I suspect MAME keeps the CPU busy enough that you won't see much improvement.
