Best mercenary so far..

i want to know what's the best by stats and f2 attaks between kunemon,drimogemon,elecmon,gotsumon and biyomon..i already know that gabumon is by far the best by having even better f2 attacks than agumon X..so i have trained till lvl 19 kunemon but it wasnt so good in champion lvl so i release it..now i am thinking to train my elecmon but it is already not compairable to gabumon..i have the other mercenaries in eggs so im thinking to hatch but i dont know what..any ideas??

I cant say offhand, but f2's are best for those who have decent hp and are more beefier in defense.
A digimon that is quick attacker but low hp/ds would not benefit from f2 leveling.
I dont own biyo or elecmon but for drimogemon, his f2's are better.
