As a user of a Xperia One IV, I can say I've been very impressed and very happy with my phone. One of the few good phones that still has a headphone jack and a microsd card slot, both of which I regularly use. When it runs out of updates at some point, I can install a custom OS on it like Lineage, so it's been awesome and I'll be using this phone for years to come. If you can afford one (since they are quite expensive, I got mine on a sale and it was still expensive), I highly recommend it.
