Thanks dude. Yeah, I'll definitely keep both. I like the convenience of AirPods as I have lots of Apple gear and they're much more seamless in terms of switching, for example, between my Apple Watch and iPhone, iMac, etc. I'll probably continue to use the Sony WF-1000XM3 more though, because they have much better bass and slightly better ANC. The AirPods Pro are great too, but I'll use them more for exercising, phone calls (haven't made any calls with them yet, but my v1 and v2 AirPods were great for calls) and 'Hey Siri' is really convenient when walking to the station, etc.
If you only want to carry one device though, I'd probably recommend the Sonys over the AirPods Pro, because of the better ANC and bass. If you don't care too much about LF bass, the AirPods Pro do sound good, though. Hope that helps.
