I went from a Pixel 6 Pro (I believe the one on the left might be a Pixel 6 Pro as well) to a Pixel 9 Pro recently and it's just about the perfect size for a phone IMO (6.3").
With a Spigen Tough Armor case, right? Had one on my 6 Pro, too, saved it from quite a few nasty drops.
When you consider the 9 Pro's screen to body ratio it's pretty compact, especially for a flagship. Ten years ago a phone of its size would have maybe had a 5" screen.
