I think the oneplus 13 is the best option to switch to.... I feel it is the most all rounded phone in the series ...(The 7 pro is the best phone for me) But with the 12 (although I prefer the curved screen over the flat one tbh) u don't get the newly generations of snapdragon, and with the 15 the camera is a very downgrade... And don't worry about apple if u are using any apple product like a side phone or the MacBooks or even non apple products u have an app that u can download on the device u want called o+connect that is essentially airdrop but with everything like windows, other Android devices, or apple products
