Update 05/22/2020 (~8 weeks for hood, ~6 weeks for roof)
What has the car been through so far?
The car has been outside 90% or more of the time. There's been lots of rain and lots of pollen. Pollen led me to washing a lot so I could see the real behavior before every rain, and the washes have been a steady 3-4 times a week. The most recent washes have been with Reset or Hyper Wash (back and forth), and prior was Four Star Professional which chewed up the LSPs a decent amount the first 4 weeks. I've now washed the hood and roof 26 times. I figured 26 washes can loosely represent 26 weeks (or 6 months) worth of weekly washing. Of course time is a consideration when it comes to durability and 8 weeks does not equal 6 months, but I at least was able to rough it up with washes and straight towel drying with PFMs (no drying aid, no blow drying).
Hood -
Pinnacle Crystal SiO2 Spray, PBL Sealant and WG DGPS are dead. I'm defining dead as less than 20% of it's original performance.
WG SiO2 PS and Ceramic Spray Coating are hanging on. Both are probably around 30%.
WG PS beads and sheets noticeably better when the car has dirt/pollen on it.
CSC catches up in beading and sheets slightly faster after a Reset wash.
Overall, I still like WG PS more because it's just less finicky with it's performance (and I think it looks sleeker, smoother). Pics below, with CSC on the mid-left and PS on the mid-right:

Roof -
PBL Synergy, Dodo Nano and AW Ti-22 are dead.
CanCoat remains a beast and I would say it's still at 85% of original strength. But on the horizontal surface the beads want to sit rather than sheet at standstill. Sheeting happens easily once the car is in motion.
PA Viking Spritz is doing fairly well at 60-70%, slower sheeting but probably has the tallest standing beads.
WG CSC maybe 50%
PBL Surface Coating is hanging on, maybe 40%.

I'll let the remaining LSPs stay for now. I'm getting itchy to try out some of my other items and might do so where the failed LSPs were. As of now I intend to wash the roof and hood 3-4 times per week still to get this test over with.
