AoL is better written -- I found both his prose and his code style more inviting -- but much more dated than LiSP. That I liked it better has more to do with not already knowing most of it, the way I did with LiSP. If you can pick it up cheaply, do, at least for history and entertainment.
A (possibly mutual) acquaintance just sent a copy my way. :D I'm off to bed, but will dig into it tomorrow. I really enjoyed LiSP, and really look forward to it!
I have TUPE too (and I was born in '82).
