I just have a smart playlist, containing 150 of my highest rated songs.
iTunes Match has been hit & miss for me. I get occasional errors where songs won't download, or appear downloaded, but the Music app skips over them completely, or my custom album arts don't get downloaded, etc, etc.
I basically use iTunes Match, to 'match' any songs that weren't from iTunes on my computer, and keep everything local, on my iPhone & iPad.
