The brand only matters if you decide to sell them.

There's an awful lot of wank about hubs. They really don't matter that much, as long as they're strong enough not to fail.

Want to know if these are good? Put them on a scale. Do they look CNCed or forged? If the bearings are cartridge, can you find replacements? And where's the ratchet and DS axle bearing? If it's like a Shimano hub with the axle bearing outermost and the ratchet inside the cassette body, good. If it's like a Campy hub and just about every aftermarket 'freehub' with the ratchet in the hubshell and 3" of unsupported axle, bad. (Shimano hubs employ the cassette body as a stressed member; it's functionally part of the hubshell, fully supporting the axle. Other hubs can hold the axle minus the cassette body and are lame in comparison; the DS axle bearing is close to the centre of the axle, and the cassette body is just dead weight from a structural point of view.)

Also, compare the flanges to other hubs to get an idea whether they can handle radial lacing. From your pic it looks like these were made for it, with more meat on the flange than older Shimano hubs, which have been known to let go when laced radially.
