In my experience the difference is similar to a pickaxe, consumes stamina faster but chops trees relatively faster as well.
Source: Had to chop down 150+ trees to clear the space for my base, metal axe definitely showed a difference in speed per tree once I made it.
Edit: I believe it is an overall increased use in stamina per tree, but in exchange you chop them marginally faster. Likely more of a sidegrade than a straight upgrade.
