I started with Droid X way back when, then moved to the iPhone 4 when it came to Verizon. Was with Apple through the XS Max till the beginning of this year and got the S20 Ultra. I have the 12 Pro Max being delivered this week. I like both platforms, but my family is all Apple and the iPhone just does certain things better.
The camera on my S20U takes beautiful pictures but sometimes I really have to make adjustments to get a great shot. The iPhone with the Sony cameras just takes great pictures. This is important at work, quick shots then send them via text or email.
Been missing iMessage, Android has RCS in Google Messages but I have about 2 or 3 contacts that use it.
Facetime vs Duo, like I said, my family is Apple so I have had to get them to download Duo. Not a big deal.
Quickshare versus Airdrop, we take a lot of pictures and videos of the girls we have that are Cheerleaders so being able to get the files to them without compression is difficult. We've been sending a lot over Whatsapp.
The 12 Pro Max new design chassis is what pushed me over the edge to go back. That added to what I listed above.
