All in all, the Find X2 Pro is technically a better deal in terms of bundles, but here are the general downsides to getting it vs. the 8 Pro:
- No alert slider (which I personally am a big fan of)
- No wireless charging/reverse wireless charging
- ColorOS doesn't update as much and as timely as OxygenOS - OnePlus also has longer support with the 5 and 5T from 2017 getting Android 10
- Depending on your taste as well, OxygenOS gives more of a stock Android experience versus a more customised skin with ColorOS
Other than that though, the screens are very much identical and you do get the great bundle, periscope zoom, 65W charging, and most importantly, native 5G support with the Find X2 Pro. So it's just a matter of picking your poison.
