I think Marth does that as though he was fencing. Fencers tend to keep a hand of their hips, but they hop around rather than walk. His sword style seems to have a basis in that kind of precision, especially when it comes to his shield breaker.
Current rotation of mains is Bowser and Dark Pit. Pittoo's a carry over from my Smash 4 mains. Dedede and Robin don't feel quite right yet though. Also tinkering with learning Snake since explosive shenanigans are fun. Incineroar and the Belmonts are currently subs that suffer from being a little too specialized, but are fun anyway.

You're welcome. They're still incredibly easy to gimp and can't risk being knocked back too far out, but that whip tether has a surprising amount of reach and is difficult to challenge if you have ideal conditions.
