Thumbs up for
@ssledoux's post. I am second to all of that.
Today went to BB and tried 12 and 12 pro. Luckily they were sitting between inch together and had a no weight anti-theft cable attached. Long story short i had a great time (30 min) of using my SE2, ip12 and ip12 pro.
Summary:
1) Iphone 12 feels much nicer in hand and the weight is almost identical to the SE2.
2) Iphone SE2 in the apple leather case is 1:1 identical in width to the Iphone 12 without the case.
3) Iphone 12 XDR display is amazing. I have airdropped photos from Iphone 12 to my SE2 and compared side-by-side.
Verdict: Iphone 12 had much more accurate and live/vivid colors, overall difference was as day and night. Then i have compared 12 to 12 pro screen, and noticed that 12 pro has a little bit better display/colors. I would say 5-10% better. But it is really hard to distinguish.
4) Iphone 12 pro was really heavy and brought back forgotten memories why i didn't buy 11/11 pro.
5) Sides of the iphone 12 looked much better than shiny side of 12 pro.
6) So i put my se2+apple leather case on top of iphone 12, and 12 was only half inch taller and that is it. All the difference is half inch taller. But the screen size increase is really appreciable.
7) Camera: I can see that iphone 12 had more complex/new lens, so the photos looked better on 12/12 pro rather than my SE2. BUT the difference was something really pixel pipping. I would say that 12/12 pro main cameras are better by 20-30% in average scenario. I took a photo of far away objects/texts, and iphone 12/pro was having 10% better clarity of the small text when zooming, but still both are readable, and when SE2 photo is not readable, then 12/pro is also unreadable. Of course i am not talking here about all that night super duper shot modes, telecamera and extra wide lens. I am talking about the main, original lens and usual point and shoot scenario in BB.
8) PWM. It was noticeable when i looked through camera, it was big until 70% of brightness, but overall it didn't feel like a problem. I used oled displays earlier in samsung galaxy s3, that also should have got terrible PWM, but i didn't notice.
9) Overall i liked Iphone 12 much more than pro. But with the only caveat - only if used without the case. If case attached, this thing will be too wide for my taste.
