I have csl+exo(varying between exo v2 and v3 toppers depending in panel)and pa cosmic (color matched v1 in hood and v2 on other areas) on my SRT
Water behavior wise, the exo beads more by a few degrees
Cosmic v2 is 108 degree ctc angle, 115+ with Cosmic Spritz on top
Exov3 is 7h and I believe close to 120 degree angle (2h if exov2-which beads a little better) though so you'll risk marring your top coat, which happened to me vs not micromarring the 9h cosmicv2
Looks wise I'll take cosmic all day.
This is a fresh coat of spritz on my 92k mile factory painted hood (with color matched cosmic v1 under)
I may not post much here but I have a couple of their products

and have been actively testing your exact posted question for almost a year.
