I've driven both - its a bit of a different feel but I think you'll be happy.
From my experience (and I've only driven an LS1 camaro a couple times and the V6 once) the V6 obviously isn't going as fast, but it FEELS like its pulling similarly, or only slightly less. I don't really know how to explain it.
Of course, if your LS1 is modded that changes things.
