Variable Neutral Density Filter or set of Neutral Density Filters

Which provides greater image quality; A single variable ND or carrying multiple different ND filters?

(I'm only asking about full ND filters, not graduated ND filters)

Of course the brand and quality of glass matters, but within brands

I've been told that a variable ND is like a zoom lens, more glass, less sharpness, but you have the convenience and lower price point vs. carrying a bunch of primes, or non-variable ND filters: less glass, theoretically better image because there is less glass, but inconvenient and much more expensive because you need a different filter depending on how much you want to stop down.

Does anyone have any insight, experience or tips in the differences between buying a variable ND filter or using multiple dedicated ND filters?  Is the image quality difference negligible?  Any recommendations on a good set of ND's or a good Variable ND filter for around $100 (62mm)?

Thanks in advance for your help!
