Grooveshark vs. Pandora

I used to love Pandora, but:

It's limiting
Doesn't always have what you want
When you want it
You can't skip more than ___ amount of songs
There are advertisements like any other radio (needless to say are ANNOYING)

Grooveshark has

More choices
You can make your own playlist
There are suggestions
There are advertisements, but they are not audible, only visual and not obnoxious and you can even remove them
