This is quite an ambiguous question, and pretty subjective as well. So instead of giving you an ambiguous answer in return, maybe I can share some of my thoughts so that you can make an informed decision as to which is best for
you.
I play both the electric and acoustic mainly, and once in a while I'll fool around with a classical guitar.
So a little about the fingers themselves first before I talk about gear;
In the recent months I have been using my fingers a lot more than a pick. I always thought that the pick is irreplaceable, that fingers cannot do hard-strumming and fast alternate picking lines. And boy, was I wrong.
Your fingers can do all that, and much more. It'll take a bit of getting used too, and also lots of practise to refine your technique. But trust me, you can do everything your pick can do with your fingers and
more!
Firstly, I think with fingers I get a nicer, rounder tone, be in on the acoustic, classical or electric. YMMV.
And with fingers I can almost be like a one-man-band. With the thumb hitting the bass-lines and the rest of the fingers doing the melody. Adding my foot in to do some tappin' and stomping, the band's almost complete.
And it feels damn shiok too, to play with your fingers, might be something about the intimacy of actually touching the strings and feeling them vibrate; very organic and slightly visceral to say the least.
As I mainly play electric and acoustic, I don't really have to choose between which is nicer with fingerstyle.
Both are nice. Both serve different purposes.
An electric cannot replace an acoustic. Nothing can ever replace a beautiful sounding acoustic guitar. And it's similar the other way round.
It'd be more appropriate to maybe ask what kind of acoustics do I prefer to play fingerstyle on. Again, it's very subjective and YMMV.
But for fingerstyle I'd go with a '00' or Grand-Auditorium sized acoustic guitar. As opposed to dreadnought of a jumbo because I find them to be a lot clearer.
'00' or Grand-Auditorium have that distinct tapered waist. Much narrower than their jumbo/dreadnought counterparts and that helps to control the overtones.
With the overtones controlled, they are much clearer and cleaner sounding than the dreadnoughts/jumbos, which are very rich in overtones. Of which make them very nice for strumming.
Also, with controlled overtones, they are also very focused, and stay within their tonal range, which is a boon in a band setting.
And of course there are the classical guitars. Which are almost exclusively finger-picked, unless you factor in flamenco players. They have their characteristic mellow and soulful tone, with a nice sustain. (Which is why classical do not have a truss-rod because the rod hinders the sustain.)
