Just by way of counterpoint, Shimano hubs , 105 or better, are simply among the best money can buy. And actually don’t require that much attention to maintenence, at least no more so than cartridge hubs. I have a set of Ultegra hubs, same design as 105, that I did not touch for two years. I finally opened them up just because I thought I should. Rear hub needed a bit of grease, front hub was pristine, like fresh from the factory. Conversely, I have a set White T11 hubs, high end, nice. In the same two years I have had to replace two seized bearings. No biggy, they are cheap, but replacing a cartridge bearing is a little more complicated than occasionally adding fresh grease to a cup and cone hub. I really like my White Industry Hubs, but next time I buy wheels, I will probably go back to Shimano.

Agree about Mavic. Their hub design is terrible, at least it used to be (google death squeal).

Updating to add, DT Swiss would be a good choice. I think they make nice hubsand their star ratchet freehub is nice. It is true that Bontrager hubs are basically rebranded DT Swiss, but I find bontrager rims are hard to get tires to mount to, which I have not found to be the case with DT Swiss rims.
