I had a Nokia 5 and it was slooooowwwww. Very unresponsive phone.
Prior to that had an iPhone which was good but had issues reconnecting to Bluetooth in my car so sold it to somebody on here.
Got a oneplus 5t now which I like.
Think about what hardware you want to use it with, eg earphones, your car, and research how well it plays ball with it.
Also think what features you want, eg you need NFC if you want to use Android (/Apple) pay.
If you're not sure buy second hand off eBay till you're sure it's what you want cos there's only so much internet research can tell you, that's what I do with cameras.
