Cameras are exactly the same, except that the Note 10 doesn't have time of flight. So far, nobody has found a reason you NEED time of flight. It's used to create 3d imaging... if you own a 3D printer, you might find it useful!
As for screen resolution, the Note 10+ and the Note 8 (I didn't own a Note 9, but I believe it's the same) shipped with the resolution set to 1080p, and most people wouldn't notice any difference. I asked my son to change his S10+ to 1440 (he also keeps it at 1080) and compared it to the Note 10, and honestly, you'd be very hard pressed to notice ANY difference... certainly, in day to day use, you won't notice it. Note 10's screen is beautiful!
The convenience of a smaller size outweighs, for me, lack of SD card slot, 1440p and no ToF lens.
Larger battery would be nice, but this thing charges very quickly, and I'm in my car four or five times a day, and dropping it into the wireless charging car mount I have requires no additional effort then I would use to drop it into a non-charging car mount!
Of course, eveyone's needs are different. My move from a Note 8 to Note 10 has been worth it to me.
