Less prone to break, better dot options, nice round window, most common optic mounting footprint. Someone might prefer the DPP which is a valid option.
Removing the optic once a year to clean and rezero is my current plan. I generally can make it without a detail strip of the extractor in that 10k-12k range.
I do use a small pin sized scraper to get build up off it and surrounding area after 2-3k.
