If verizon is still 100% CDMA then no, the exynos only works on GSM.
Last year the snap was better on battery then exynos but every year previously it was the other way around. That said i have no problem getting 6hrs SOT on my exynos note 9
The snapdragons have always had better GPUs as well
I'm pretty sure I just bought an Exynos version off of Craigslist. It was brand new, still with stickers and wayyyy less than I would've paid anywhere else. It's dual sim, unlockable bootloader, and when I looked up the ESN online it came up globally whitelisted by Swappa. I also checked each carrier on checkesnfree.com and when I searched AT&T it identified the phone as a Korea S10+. The model # reads SM-G975F.
All of that said, I'm on Verizon and it's working perfectly so far.
I have an S9+ (snapdragon) and I never rooted it because some features would be permanently disabled. If I unlock the bootloader on this phone, would it disable those features (Samsung Pay, etc). I'm a recent Pixel convert and I could unlock them and as long as I didn't root, those type apps worked fine.
If I won't lose any features I'd prefer to unlock now since I haven't finished setting up this phone yet.
