Maybe I'm old school, but I just can't get used to auto darkening hoods...even in the shop. Never was taught using one, and we can't use them at work anyway, spaces I have to work in are just way too tight, those big ass hoods would never fit anywhere. Plus welding with a mirror is pretty much a daily occurrence where I work, and the sensors will not trigger if the arc is being transferred through a mirror. Just a regular 2x4" passive shade 11 with a flipper for me. I've been making my own hoods for quite some time now out of leather, best hoods money can't buy IMO.
