I am using OP3. OP3T has few differences than the OP3. The design and everything you see outside is the same.
Pro
Cons
Hope this helped
Pro
- No Lag what so ever
- Plenty of Space 64GB. (Not expandable in OP3)
- Constant updates + security updates.
- Customizability.
- Slow mo recording.
- Low price.
- Fast charge (30 Mins to full charge) - This is awesome

Cons
- OP3 Front cam sucks in low light. Back cam is good though.
- Battery life is not good for a heavy user. I play games and I charge my phone nearly twice a day.
- Few Bugs in Oxygen OS.
- Slippery as hell. Dropped 2 times already

- USB C cable. You have to have a secondary cable in case you forget not everyone has USB C cables.
Hope this helped
