I went with the XD purely because I did not see the worth in the increased cost of the G26. I'm picking up my XD9 today
You will see it when you buy parts, and upgrade the trigger.
Glock trigger upgrade $20 max and very easy to do.
XD trigger upgrade $130ish and requires some skill.
And you will see it in resale, Glocks tend to have a broader market so they tend to run a little higher used.
