This is something I'd also like to know.
I've been riding a 2x10 this season and I am not in love. With the 26-38 front and 11-36 rear. The 38 is too large for local trail riding so I end up in the 26 for the bulk of my riding. Somewhere like Bend or Sun Valley and this wouldn't be an issue.
I like the ability to make large jumps with one shift in the front, I've never had problems with front mech being some evil thing I hate. I've had other front issues of keeping the chain on, but it's not shifting based.
I have the same setup as you. I have been using the 38 a lot more lately now that I am confident that I have the chain length to run all the way to 38-36 if I need to (chain line be buggered). Not saying I do that a lot, but I will routinely go to the third largest cog on the rear if there is a short uphill section to clear. I like the reduced chain slap/chain drop of the 38t plus I seem to hold momentum better. Plus, my bike is possibly a bit plusher in the 38 than the 26 due to suspension geometry (but probably more due to perception).
I generally find (on Fromme anyway) 26 for the climb, 38 as soon as I hit the trail.
