Thanks for the pic comparisons. Which one do you prefer in hand?
The weight and thickness is noticeable both just holding the case as well as on the PM.
Air is spec'd as 0.65mm and EZ as 0.85mm. For reference, 10 sheets of paper is about 1 mm or a credit card is about 0.76mm.
Air weighs 9g and EZ weighs 17g. Totallee clear, soft TPU case weighs 24g.
I use a tempered glass screen protector on my PM so there is really no "lip" which I prefer for gestures. If you had no screen protector there would be a minimal lip above the screen.
If I never tried the Air, I would be very happy with the EZ. I have used the EZ on past phones (and on my PM while waiting on the Air) and enjoyed it as it is very light and thin but still provides some bump protection and definitely more grip than a naked phone.
The Air just takes it up a notch for a big phone like the PM. If you use the other Pitaka accessories that utilize the magnetic attachments, then EZ is the way to go rather than trying to rig up something in the Air. If you don't then Air is a great option.
The other thing, over a naked phone, is the Pitaka Air or EZ "softens" up the edges of the phone by the case. Hard plastic cases or the naked phone had a tendency to dig into my pinky when holding the phone with one hand for extended periods of time due to the size and weight of the PM. The Air and EZ both provide a softer feel, IMO, when holding the phone with one hand resting on your pinky.
Air is not quite as "rubbery" feeling as the EZ and likely due to the tighter weave and thinner case which makes it a bit smoother if that makes a difference to you.
EZ seems to have a bit better grip for this reason, but Air is still very good and better than something like the Totallee clear, soft TPU case which is generally recognized as the thinnest clear case and one I have used on many phones in the past.
Both show fingerprints but they can be wiped off if that is an issue for you.
