I use them, both in regular buffers and in the minibuffer, so at least I 
speak with some experience.

I would make a distinction between two things: (1) vertical display of 
completion candidates inside regular buffers (what Company does) and (2) 
vertical display of completion candidates in the minibuffer.

I agree that for (1) a GUI vertical list widget could make sense instead 
of the pseudo-tooltip that Company creates with an overlay.  I would not 
use such a widget myself, as I like the minimalism of a terminal-like 
interface, but I understand that others could prefer a more modern UI, and 
could judge that a pseudo-tooltip is "unprofessional".

I can't agree that for (2) a GUI vertical list widget would make sense, 
IMO it would be awkward to use a GUI widget there.  If AFAIK none of the 
packages that implement vertical lists there create an rectangular overlay 
with a pseudo scroll bar (as Company does) to mimic a GUI vertical list 
widget, it's probably not without any reason.

Indeed, I agree to fundamentally disagree.
