Haha. It depends on what you like. Kuffdam does mix sets, where's Tiesto does mainly Radio show-like podcasts, and occasionally (once a month I think) releases a recorded mix-set as his podcast.
I do love my mix sets more than hearing a DJ's (even the God that is Tiesto) voice every 8 or 12 minutes.
Another good podcast is Jordon Waeles' "Trance Mutation". Infact, this is my favourite. It's better than sex sometimes.
