Is there a discernible difference or is it one of those things that you need to look hard to see a visual benefit of the Crystal Serum over the Opticoat?

Honestly, when it comes to coatings, most of the high end stuff are very similar, just with subtle differences.
Maintenance is the key for longevity of coatings. A very high end coating that's poorly maintained will last just as long if not worse than a mid-range coating applied professionally that's properly maintained.
Personally I'd go with Gtechniq, as in my own personal experience it's easier to apply, performance is great. So less of a chance for an installer to really mess it up.
Installation and prep trumps the actual coating itself. With a crappy prep, and crappy installation even the best coating won't last.
