Considering iTunes match is one of the best things I've ever used I'm going to say no sarcasm and that you're in the minority.
I have 15,000 songs in my iTunes library, the vast majority of which are not on Spotify. My 16GB iPhone would normally only hold a fraction of my music but with an iTunes Match subscription I have access to it all.
Also, it gives an off-site back up of every matched song. So tell me, how is iTunes Match similar to Spotify?
