It depends on your preferences and financial abilities. 1. If you have plenty of money, and care about the fame of the phone, go for the latest Note and S series. 2. If you have little money, but want good specs, go for the J series or the M series, they're quality phones for a good price. 3. If you are somewhere in the middle you can go for the high end A series (like A80, for example), and you'll get a good phone. 4. If you don't mind not having the latest phones, you can go for a Note 8 or an S8+. Good luck!
