This is anecdotal evidence at best, but my experience is that you get used to whatever is in your hand.
My first guitar that was actually mine and not borrowed was a Charvel (owned by Jackson as it happens) with a very thin neck. It was of the "superstrat" type where it resembles a stratocaster generally but has aims to improve upon that with some modern touches. Basically, it was a shredder guitar, though I was not quite a shredder then in first year or two of playing. It has a very thin neck.
But a couple years after I got that guitar I gradually transitioned from metal to jazz as I learned more about music and got lessons and went to school etc.
That shredder guitar was not ideal for jazz but it worked for a long time. And because I didn't really have the money for a more tonally appropriate guitar I kept using it for a long time past when it was really appropriate. But it sounded fine and felt good in my hands.
Then at some point I got a semi-hollowbody which was much better in terms of the sound that I wanted, but it had a much thicker neck and I worried about the playability. A few weeks into the new guitar I realized that not only did the thicker neck not matter but now playing my Charvel felt weird.
In summary, you'll probably get used to it. If something is really bad or not for you, you'll probably know. If you try both and it's not a huge deal to you, you'll probably get used to it in time. If you play an instrument long enough, it will feel like home. The trick is to play enough different instruments so that you can get an idea of what home best suits you.
(All things considered, I think I preferred both the thinner neck and the tung oil finish compared to a polished neck. Faster is a good way of putting it. But, seriously, I got used to it and would not trade back given that I like my sound so much more now)
