First, it's important to know and be aware that the Google Pixels are not "great phones." There is a long-standing issue with SMS and phone call reliability on these devices that Google doesn't want to acknowledge, let alone fix. It's not something that affects the devices in a way that most people will even notice as it basically is a drop in reception to where incoming calls won't ring the device (or your caller will tell you it rang a bunch of times but you only heard one ring or similar), text messages (SMS specifically) won't deliver, and then things will go back to working correctly. The drop-outs have no fix and I know full well that Google is 100% aware because they ended up taking my Pixel 6 Pro back for a full refund because they had no fix.
A second, possibly related, issue is that the device goes into a sleep state where no inbound communications are received of any kind. I've had my devices sitting on my desk while working from home, connected to WiFi, plugged in, and even fully charged (while plugged in). The phone provides zero indication of texts, calls, emails, etc. All the while, I see pop-up notifications and hear alerts on my computer for emails and other incoming communications. Pick up the phone and it "blows up" with every notification trying to alert all at once like they've been queued up and waiting.
Second, the reason that Google isn't taking any market share is because they kind of can't. Apple Fans aren't going to switch because they've bought into the "blue bubble" idiocy. Samsung fans aren't going to switch because Google isn't going to actively try and compete with their biggest source of data via the Android operating system. Pixel devices are updated much more quickly than other Android devices and this is a very good thing. Samsung isn't going to take that on because of their add-in bloatware - they will leave the updates to the carriers which is a horrible approach for the consumer as devices are left unsecured (without patches) for sometimes months on end because of delays with carriers pushing them out and no way to get the updates directly for the consumer.
I've owned the 2XL, 3XL, and 6Pro - loved them all until I finally got 100% fed up with the phone/SMS issue that became an issue I was no longer to deal with when the ability to get me via phone/text became 'critical' (and I was missing calls and texts were delayed). I've since switched to a Samsung but am literally months behind on security patches because of major lag in distributing their version of Android 13 to the handsets. I use all Apple products for my compute needs and have an iPhone for work. So, there's no reason I can't easily switch to an iPhone for personal use.
