Head to head test of the AIOs I have in my garage (I didn't test DG 105 or Prime Strong, due to similarity with others in the test):
Klasse AIO
Werkstat Prime Acrylic
Werkstat Prime Carnauba
Duragloss 501
and threw in LSPs for comparison:
NXT 2.0 (liquid)
Collinite 915
Photos below. This is on the roof of my 1999 F150, which has plenty of hail damage, etc. and seems to be fairly prone to water spotting. It sits in the weather 24 hrs a day and I drive it to work most days. I wiped the surface down with IPA, polished it with 106FF, then wiped it down with IPA again, just to try to be sure I was starting from a clean surface that wouldn't influence the results. I applied each with a separate applicator and buffed with a fresh surface on a microfiber cloth. Only one layer was applied and nothing was used on top. I usually wash the truck every 1-2 weeks and plan to continue that for this test. I'll post periodic updates showing beading, any water spotting, and I'll try to report slickness on a scale of 1-5 (5 being most slick).
It's overcast today, and I can't tell much if any difference between any of these except a slight difference in slickness. They all went on easily, probably KAIO and Prime Acrylic were easiest, but none were hard at all.
Slickness immediately after buffing:
