Just a personal viewpoint coming up, I realise that loads of people here love choosing tuners and stuff........
I wouldn't have a custom guitar or bass made for me as I have no idea what tuners I like best and don't want to invest any time/effort into finding out.
I prefer to just buy an off-the-shelf guitar and let the manufacturer make the choice.
Sorry to not really answer your question, hope you get some meaningful answers from others!
