I liked the gold and silver on the 7 series, when they started doing the glass backs on the 8 and above series, the silver looked white and the gold looked pink.
Personally, I don’t like any gold or silver 6,6s or 7 series. The antenna band just too obvious to ignore. The jet black iPhone 7 hide it perfectly.
But no one today should go buy jet black iPhone 7, or any iPhone 7. Since it stuck with iOS 15 forever.
Oh well, sub-100 dollar is okay for backup phone. iPhone XS is the minimum for now.
