Do I need a digital level or is a bubble level enough?

For most leveling and plumbing, a quality spirit (bubble) level is enough and never needs batteries. Reviewers in r/woodworking and r/Tools reach for digital angle gauges like the Klein 935DAG when they need to match or transfer specific angles, set saw blades, or read tilt numerically. The trade-off is that digital units rely on calibration and reference off whatever surface they sit on.
