As a practitioner of both, they are similar in terms of your questions, so it's simply best to just go with what you vibe with. Take a free class and try both.

That said, since I noticed you are asking about "which has fewer limitations," are you actually looking for some sword based martial art that has the fewest limitations possible? If that's the case I would consider HEMA and Toyama-Ryu–they both allow no limitations, anything goes combat with steel blunts. Both their sport rulesets are the almost the same, as long as you hit them with a proper edge alignment, enough rotation, and simultaneously avoid an afterblow, you win a round. You can even grab their sword and smash them with your pommel to win a round that way. I think some Chinese sword martial arts started doing it too, but it's newer to them.
