Just my opinion: It's probably a mistake to ask other folks what works with a given hand size. It's an individual choice and there are lots of factors.
Folks are all over the map on neck sizes and shapes. I know lots of players with smaller hands who love thick necks, and others with very large hands who prefer narrower or thinner necks. It's impossible to predict.
That's why I tend to say 'try them yourself'.
When people suggest that for certain size hands, 'get the such and such neck', I feel they're unaware of an awful lot of individual factors.
For example, It isn't just about the length of palm and fingers - in fact fingers can be long, palms short or vice-versa, merely considering hand size measured from bottom of palm to tip of middle finger is kind of irrelevant!
Hands also come in different widths, different finger spacing from outstretched thumb it to tip of pinky finger, etc., different finger thicknesses, etc. Some folks can stretch their fingers apart very widely, others (like me) can't.
And there's stuff like grip size that gets measured and factored in - often measured when picking out sports gear.
The anatomy of each hand is different. What's comfortable for every individual's playing style is different. For example, do you play with fingers curled or flat? Hook your thumb over the fretboard edge or not? Need to reach for difficult distances to play chords? Do you like widely spaced strings, or find narrow string spacing preferable for picking speed and accuracy? Do you play with a pick, fingers, or both?
I can only use myself as an example.
My hands are somewhere in the medium-to-large continuum, depending on how that's being evaluated. But I can't stretch my fingers out all that widely. Certain chords are uncomfortable to play. That affects the chord voicing I can manage.
As an example of being all over the map, I like the string spacing on the Pattern Regular, it's more like what I learned to play on, which is a factor to consider, too (we sometimes develop picking habits pretty young). I curl my fingers because my main instrument has always been piano, and that's what feels right, because it's the proper technique for piano. Of course, that affects notes I can comfortably and quickly reach when I do that on guitar (one of my session guys who gave me a few lessons tried to get me to play with flatter fingers).
Despite my high regard for the Pattern Regular, I
love the feel of the Pattern Vintage. By pure luck, It happens to sit in my hand comfortably. Yet they're very different necks! Go figure.
And I have two with Pattern necks. I've never had a problem with that carve (or the previous wide/fat).
The only way to choose a neck carve for a custom instrument is to sit down and play each for as long as you can. Try different things, different chord voicing, arpeggios, runs, solos, you-name-it.
The dumb mistake I made with my PS acoustic was to pick a 1 3/4" wide 'finger style' neck width. I was more comfortable with my earlier PRS acoustic that had a slightly narrower width, and knew it. But I got all optimistic that I'd switch after all these years to finger style. Never liked it, and went back to a pick. Yeah, pick the neck you know works, instead of the one you think you might like down the road! Doh!
So the wider string spacing bugs me a tiny bit. I have to adjust to it every time I play and warm up. Nonetheless, I love the guitar. I just wish I'd played a bunch before deciding.
I guess that proves things don't have to be perfect - I'm pretty adaptable - but it was certainly an unforced error!
