I also prefer the shimano system for everything except high dollar stuff.

Why?

well the shimano hubs are cup and cone and serviceable. and you can flush the freehub with oil while you have if off.

the rest of the cheap systems are not that servicable and adjustable. not shimano level at least.

also shimano makes maybe 10-100-1000 times as many wheels as vision and mavic combined, so its highly unlikely anything they make is actually better for a given price. they have the real mass production capability. and with mass production comes low price for a given quality.

------------

You are probably just wasting money up to maybe 500-1k€ level. then you may get better quality.
But they might not be better durability. since all expensive wheels are 20/24spoke or less. and thats not really a durable choice. 32/32 is.

I actually managed to build 200g lighter wheels than my shimano rs010 set. the shimanos were 120-130€, and they needed to be cracked open for gresing and adjustment when new. as all shimanos!

i got Archetype rims f/r
dt240 f/r
54t ratchet
28/32 spoke dt comp 2,0-1,8-2,0mm, brass nipples

and they are 200g lighter than the shimanos. AND more durable, and probably more aero. and only 700-750€ or so more expensive. (only lol)

and i have noticed absolutely nothing is speed gains. physics, unfortunately. 200g is not gonna turn you into lance.
