I think it really depends on preferences and how the rider is going to use the bike. If you're commuting on mostly level terrain, I imagine any of these ranges will be more than adequate. If you're heavy on the throttle or assist or if you're super fit, a 380% or smaller range might be fine. But if you still want to use it as a regular mountain bike and/or you like that 22/24T chainring up front in your double or triple chainring crankset (or maybe you even use a 26T in a 1x setup!) or if you tow a trailer(s), you're probably going to want that 526% range.
For reference, the Frey bike has a 418% range.
Having more closely spaced ratios can be advantageous to road (and even MTB) riders that are looking for the perfect gear to maintain an optimal cadence. Road cassettes have much more closely spaced ratios.
Cars are coming out with 10-speed transmissions now =)
