I voted for epi because I think it's simple and classy, yet the grains/lines in the leather can give it a casual spin if necessary. I think the vernis truly gorgeous, but I don't know if it'd hide any scratches as well as epi and I'd want to be worry free.
I just made this decision the other night lol. In the end, I went with the epi electric noir over the vernis (I was only considering these 2 cause think the others are boring...) because:
the epi still has pizazz and is attention grabbing but in a more muted way (if that makes sense?!), I liked the silver hardware better, the interior is microfibre vs the linen type lining of the vernis, and I believe the epi will be more timeless than any given vernis colour. It will always be appropriate and can be dressed up or down.
Overall, I think I'll be able to wear the Electric Noir for the rest of my life! lol
