I have the novatec hubs laced to tb14s. I've not had problems over my admittedly low winter milage. I'm pretty sure novatec parts are easily obtainable and the bearings are probably a standard size so could be bought from skf or similar.
My main reason for buying them was they were very shiney. The have a louder clicking free hub than my 5700. Other than that I doubt you'd notice the difference.
