Pick the Shimano XT M8100 if you want the most serviceable, longest-lasting MTB clipless system on the market — industrial-sealed bearings, field-replaceable axle, and the cheapest cleats to replace. Pick the Crankbrothers Eggbeater 3 if you ride muddy, rooty terrain or need 4-sided entry for quick clip-ins — the open spring design sheds mud better than any cage pedal.
Shimano XT M8100 — lower long-term cost per mile; cleats are half the price and last longer.
Crankbrothers Eggbeater 3 — lighter, 4-sided entry, and mud clears through the open body.
