A Nothing Phone 1 honestly sounds like the better pick. It's a young company, so there are no guarantees the support will be good — but if that's not an obstacle, it's a better device. Clean Android, good overall performance and of course great design. Just check to see when the device ships... you don't want to wait weeks to get it.
The division ce is already available in stores and my grandfather chose the one plus as he felt that he was used to the interface and did not want to change ( his old phone was a oneplus 5t)
i found 2 contenders for the phone
1. Oneplus 10r 5g or nothing phone 1( keep in mine he already uses a oneplus and is used to their interface)
