It's hard to tell on Weaponsmiths right now because GU 45 added per 8k new recipes to the game, all WS and WW weapons (and imbued versions). It will certainly be easier to level, and I can tell you the new Woodworker versions seem to be selling decently, but I think the jury on sustainability is still out.
I don't use my provi much, but IMO if you used yours a lot and liked it, go with that!
