How stock are they these days? I had a OPO but thought they had changed direction and made a more customized OS for subsequent devices.
Very stock, at least the OnePlus 2 and 3, they actually have some very useful but optional and non-intrusive features that actually end up in later stock versions of Android like Marshmallow and 7.0.
For example, app permissions were on the OnePlus 2 before Marshmallow came out and that feature in 7.0 that lets you hold the back button to "alt-tab" to the last open app is also already there before the 7.0 update. And usually all the features are implemented in a UI/UX way that Google would end up doing it anyway, or very similar to it.
