I say go for it.
When you get down to the fundamentals all of the suppliers and vendors have about the same process and results.

We do DLF and ceramic coatings in-house.
I highly recommend the DFL, I've even done several builds using good used bearings that I DFL coated. Perfect treatment for used piston skirts and uncoated new.
Ceramic IMO really only needed in higher performance builds, high CR & HP.
The cost, the coating is cheap, it's mostly labour. There's fair bit of prepwork, clean, process, bake, then polish . Everything has to be spotlessly OCD clean.
I agree the coatings, whoever you use, are basically the same.
