I had a OP1, OP3, OP5 and OP7 pro or something before I switched back to Samsung. In the beginning they were flagship phones being sold for half prices, lately I've even forgotten about them.
Good call. I've got the 8t and it's horrendous. I bought because I kept hearing good things about their earlier models and figured it would translate. It didn't.
Next will be a pixel for sure.
