Which driver should i get? [Low effort]

The word on the street is that linear will give you a tiny and temporary increase in output but will dim as the battery discharges. It also runs hotter.

The buck boost is more efficient, runs cooler, and will give you consistent performance for the entire discharge cycle of the battery.

The buck boost driver also does not have thermal regulation, so that’s something to consider.

All that being said I prefer the buck boost.
