Well I'm with you on enjoying the PT. I thought RotS was as good as Empire and I think TPM is underrated. AotC was pretty iffy, though.
I don't think I'd say ROTS was "as good as ESB", but I would say that ROTS is my "favorite" Star Wars film, despite its flaws. And I agree that TPM is underrated.
AOTC ... while its final reel was a HUGE crowd pleaser when I saw it during the midnight release in Times Square, sadly, the film as a whole just doesn't hold up to repeat viewings as well as the rest.
