Absolutely. STV is the dream system. Proportional representation but with fully local representatives.

My favourite feature is that it holds politicians directly accountable to their constituents. If you don't know much about politics, you can just vote by party, like regular ranked ballot. But if you know more, you can rank individual party members against each other in the same party. There are no "safe" seats party insiders can hold to assure being elected, keeping everyone accountable.

MMP either has party lists (and its potential for corruption from seeking higher list rank from the party), or systematically over-represents areas with more fractured political views. MMP also can lead to more fracturing of parties, since you only need a very small percentage of votes to get 1 seat, instead of 20%+ (locally) to qualify for a seat in STV. We don't need single-issue fringe parties holding the deciding vote(s) to get to a majority coalition government able to force a snap election at any time!
