I've used Pure 2 since the '80s. I liked it best of all the fluids commonly available back then. I tried AI one step and sometimes results are okay, but Pure 2 is usually noticeably better. I haven't tried L'Art. I like the idea of just one step and I'm happy with results. I tried AI out of curiosity to see if the occasional bit of noise could be eliminated. Most records that I got new or in NM cond are dead silent most of the time. If L'Art is the best, Pure 2 might be a better alternate.
