Should I get an adjustable dial or guard combs?

Reviewers who prioritize dialing in an exact stubble or beard length tend to favor stepless or fine-dial systems like the Panasonic ER-GB42's 19-setting dial or Manscaped/Beard Club-style wheels. Guard-comb kits like the Philips Norelco multigroomers are more versatile for body and hair but offer coarser jumps between lengths.
