Hello, I am strongly considering switching to GrapheneOS and a long time Pixel user on Verizon (currently Pixel 9 Pro XL). I am looking to get a Pixel just to use as a test drive device and learn how to use GOS until I am ready to make the full switch. Is the Pixel 9a a good phone to do this? They are currently 400 USD on the Google Store...is there any reason to pay more for a 9 or 9 Pro? If I decide to make the switch permanently, I would upgrade to a better model, so this will solely be used to test out the OS and see if I am ready to go all in. Thank you for your time and replies!
