As a group, the quality is a bit all over the place. Some versions are great. Some are not.
The ones you listed, including the one that started the whole subset, are among the ones widely considered great.
Opinions on the play procedures and rules will vary, of course. Generally speaking, the rules are far more player facing and players are more involved in driving the game. Characters have Playbooks, which is very much like class, but lists all the different special abilities and moves for the character. There are also basic moves available to all. These moves have outcomes that will drive play based on the results of a roll.
It is a bit of a change from D&D and similar games, although probably not as big a change as some folks may claim. The game is meant to eschew the prep heavy, GM-directed play associated with D&D and similar games, and is instead focused on finding out what happens during play. The mechanics are designed to promote this. The idea is to not have a pre-authored plot where the players simply have their characters proceed along the predetermined path to complete "the story".
I'm currently playing in a PbtA game of Stonetop, which is a take on Dungeon World, and so far it's been a lot of fun.
