My faves to play are Deal and Althea.
My wife loves Ripple and seems to request it every time the grandkids are around (even though she is not really into the band).
Went to a lot of their shows in the late 70's. Also saw Jerry's band a few times. Not really into the current versions all that much (some of the tempos are kind of slow for my taste) but I did see them with Mayer a few years back and enjoyed it.
They are in my top 3 favorite rock acts
