36h rims ARE significantly stronger, something like 20% IIRC….. BUT, do you need that on the front? That’s a different question. On the back, yes, more spokes is worthwhile, not so sure it is for the front…. Although you won’t notice the extra few grammes so why not, if you think it might be worth it?
IME (And others) CRC wheels are best regarded as a cheap kit of parts, and then you can finish the build yourself. Mine were the only wheels I’ve ever had go ‘loose’ even though they were built with DT Swiss Pro Lock nipples which should stop that sort of thing. I retensionned them myself and they’ve been fine ever since. Merlin build better wheels IMO. I can build better wheels myself than both of them, though, and I’ve only done 4 so far….
