I went with ZZ Top. I really hate the song "Legs" but nowhere's near as much as I hate "In Your Letter" which is the song that Killed REO Speedwagon for me. Other than "Legs" that whole ZZ Top album is great. Hi Infidelity does have its moments "Follow My Heart" is probably the best song on both of the albums in this poll but to me there's only another 3 or 4 songs on Hi Infidelity that I can say are decent to good & the others are just fluff.
If you ask me what band I like better I'd go with REO but between these 2 albums....ZZ Top Hands down
