For me it's more about which ones are most forgettable or just not up to par with their best work. But even now, as I listen to clips double-checking my instincts they are all still good on some level. But gun to my head I'd probably go...
In hindsight, yeah there are a few that have worthwhile bonus stuff. III and Phys Graffitti come to mind with the alternate takes, and I think III was the one with king of the highway and jennings farms blues? PG had that brandy and coke version of trampled underfoot, I really liked that. and I think coda had that 10 carrot pod song? (or prescence? I remember coda being kind of a slog). Most of the demos and alternate/rough mixes are pretty forgettable IMO but III was the one that I found most interesting. LZ I was the deluxe I thought was weakest -- just a live show (when they were young and really had the fire, so it's still great,) but nothing revelatory about the songs or the process of getting the album to where it wound up.
I’m gonna sell a batch of the deluxe editions of Zep 1 through 4 . Just a heads up if interested
oh my. I ended up picking up I, II & HoH in the standard editions but this is the type of offer that tempts me mightily despite all logic. DM me.
