I've subscribed to MOG, and I currently subscribe to Rdio, but I've been itching to try Spotify for what seems like a year now.
My early thoughts:
1) The software is snappier than, but not as well designed as Rdio.
2) Their catalogue is missing a lot of work from some of my favorite main stream artists (Bob Dylan is the biggest hitter I've encountered so far with a woefully incomplete discography).
3) No web interface like Rdio or MOG, so you're out of luck on a work computer where you don't have full rights to download and install software.
4) Being able to add in your own music files is nice plus since neither service has 100% of what I want.
5) Having an ad supported free version is great for sharing playlists. I've made Rdio playlists I'd love to share with their embeddable web widget, but only people with a paid Rdio account can hear the songs. With Spotify you don't get a web widget, but you can share playlist links which anyone can listen to with a free account.
