I've had sync 4a with the big screen for about a month now. I previously had a 2019 Expedition and to me, the upgrade to the bigger screen and the updated sync system by itself was worth the upgrade in vehicles. I felt like the previous version looked and performed like a very dated system - in fact this was the one thing I disliked from the day I bought the 2019. The new one is responsive and intuitive with a very modern/techy look. It only took me a few hours really to get used to not having physical buttons and nearly every gripe I had with the old system has been addressed. There are still a couple of things I think they could improve (camera functions/ease of switching from front to back camera for example), but overall I'm very happy.
I am a tech person in general and prefer to have the latest/greatest, so if that doesn't really matter to you, the other upgrades in the 2022 are fairly minor in my opinion. I do like the updated styling of the front end and I went with the stealth appearance package which I really like, but I do not notice a lot of difference in the drive or general features of the vehicle.
Two side notes - a feature that I lost in the 2022 is the ability to change the ambient lighting color. Not a huge deal to me, but my kids always enjoyed picking the color. Not sure why they got ri of this ? Maybe a chip shortage issue? The other note is that I did recently have some type of electrical/sound system issue where my speakers starting making a horrible and loud noise that I could not get to stop for about 5 minutes. It hasn't happened again, but there were a couple of other one off glitches which does worry me that there may be some kinks that need worked out.
