Those really don't solve the same problem. Personally, I've found a lot of stuff that could be a figma or drawio (or inscape etc., yes) are more effective being a PUML or DOT or MetaPost file (or whatever format floats your boat) - not because it's easier to make (it isn't) but because it's much easier to change coherently and they change a lot. You can version control it better also. If you want a prettier final form for some sort of final frozen version, redraw it in whatever tool you like.
