IMO the 17 Pro feels nicer in the hand than the Air. I know that may be an unpopular opinion but the Air is wider and although it’s lighter and thinner than the 17 Pro feels a little more unwieldy than the 17 Pro. The 17 Pro although thicker and heavier, isn’t as wide as the iPhone Air and it just fits nice and snug in your hand with no need for finger gymnastics like you still need at times with the Air.
I don't disagree with this either. It's just a better one-handed form factor, even if "chunkier" or heavier. Finger gymnastics is a great term, and I'm in the same boat - still have to use them on the Air one-handed, even though it's very nice to hold and use in general.
