I am far from unbiased as I just switched back to my pixel 4a from my new Sony Xperia. I think the Pixel 4a is a flat out GREAT phone, full stop. It is perfectly sized IMO, has been very reliable, good battery life (though at this point I should look into replacing the battery), and it has a headphone jack. That being said, picking it as a new phone now essentially means going with a custom rom and hoping it stays supported. That's fine and all, but it's not something most people want. Just to be clear, the xperia isn't a bad option per se, I only switched back because the phone came carrier locked when it was supposed to be unlocked and the carrier it was locked to was uncooperative so I refunded it.
