I have Lotus pressed in Holland. The quality of Holland mastering and vinyl is very good, not sure how it compares to Japanese pressing. The recording is pretty good although a little bass shy. Mix is very heavy/up front on Carlo's guitar, unfortunately keys are recessed a bit too much and overall sound is a little flat in terms of sense of space and stage.
I've had Moonflower on U.S. pressing, and Holland pressing. Holland Vinyl MUCH better; cleaner, clearer, more detail, less distortion... better recording quality than Lotus... drums hotter and with greater dynamics. Not all of Lotus is live, there were some studio cuts, some cuts are, like all Santana, so-so artistically speaking, others are great. If you sit down and listen to Moonflower all the way through you'll probably end up with a headache! I love Carlos but after an hour or so you want to get off the ride.
The Buddy Miles thing has never been recommended and I don't have it.
