I just bought iTunes Match and I hate it! I was under the assumption that I could sync my iPhone normally as well as access iTunes match. However this is not the case. When you enable iTunes Match, I lose all the playlists I have on my phone. 90% of the time I use the recently added playlist to listen to all my new music. So I wanted to use iTunes Match to access the rest of my music library that can't fit on my iPhone. In my opinion iTunes Match is useless until Apple integrates both local syncing and cloud streaming.
