It depends on how particular you are about the setup.The biggest issue is: can I get something that’s stock and ready to go or do I need to build it myself and have a tech finish the nut/frets for me.
In my experience, Warmoth necks are certainly playable without nut or fret work, similar to what you'd get if you bought a non-Custom Shop Fender. They can be perfectly dialed in with some attention to the nut slots and a fret polish. I've received a few that needed to have a slightly high fret or two leveled, crowned and polished.
