Since this has not getting attention i figure I would chime in.
From other pros I hold in high regard it seems Aquapel is still the champ on glass as far as water repellency and clear vision. It seems opti-glass may be more durable, but initial water repellency is slightly lower than initial aquapel, and opti-glass' performance decreases quickly after that while aquapel holds up better in the mid term. Aquapel lasts for a good 4-6 months super strong on my cars, not sure if it falls below opti-glass after that. I have not used the opti-glass myself, though, still have plenty of aquapel and do not think it is worth for me to try ($) the og out as of yet.
