The DLC is great, no doubt about that, but if you are trying to get your rep as close to gen as possible, then you need the correct PVD. As far as I know only 2 people ever did that. Finepics way back when, and the company he used got taken over and won't do it anymore (in the UK I believe), and Rolli. No one else has colour-matched the PVD perfectly apart from these two, as far as I know.
However, if you are not bothered about getting your watch close to gen, then DLC is fine if you prefer that
