I like the Winery Dogs and Oysterhead, but I agree with Audioslave.
I think Winery Dogs got it right by having a songwriter on board in the shape of Richie Kotzen. I pretty much lost interest in him back when he joined Poison (Ugh!), and missed out on his stuff up to WD. There's plenty of noodling, but enough song going on to make it a winner for me.
Sons of Apollo... some of it I like, some of it I don't... the jury is still out...
