The Exynos modems range from nightmare to simply not as good, specially compared to Qualcomm but nice upgrade. At least something.
I ditched Samsung (after 1 attempt to use Galaxy) mainly because of the modem. Although it has now been rectified by eliminating the Exynos version in EU, can’t switch back.
On the other side, the wi-fi modules are top notch.
Exynos is terrible and is one of the reasons why I'll never own a Samsung phone. I tend to buy only Qualcomm phones because in almost all cases they are fast and battery lasts longer. Generally, I never had issues with Qualcomm phones, but Exynos, dear God. Samsung should stop embarrassing themselves and just use Exynos in home appliances because that's the category they are only good for.
My next phone will definitely be either Xiaomi or Motorola. I fell in love with my Poco X5 Pro the moment I opened the box. Yes, it came with A LOT of bloatware and ads, but really nothing you can't get rid of. I just connected my phone to a PC via ADB and some software, I managed to remove pretty much anything I don't need in less than 5 minutes.
I removed all Xiaomi apps (except Security which can't be removed as the HyperOS will boot loop) and replaced them with Google ones which come with Pixel devices, even the basic ones like Calculator. Modem inside this phone is a beast! I never had any issues with Wi-Fi or mobile signal reception at all. I just love it.
Motorola phones would be my second choice, they are made by Lenovo from which I have Legion laptop and I'm really satisfied. Beside, my father owns Motorola phone and after buying the first one, he only wants Motorola now, nothing else. I like the fact they have clean Android with just a few bloatware apps, nothing else. Pretty much Pixel experience for half the price.
