Just personal preference I guess. I never get a bad cut and I prefer the mouth feel of the V Cut.Why do you feel a V cut is superior?
Regarding "not messing up the cut" the Perfect Cutter resolves that for all but the smallest ring guages (think Purito here https://www.perdomocigars.com/10th-anniversary-champagne, or smaller), where it can overcut. Corona and up it works perfectly every time.
I don’t think it’s superior was just interested in what people used. Some use a finger nail. I’ve used a knife in pinch.
