I am comparing these two pokemon because they are very similar they both have the following similarities.
 
Golbat and Kabutops have each got
 
60 Hp
a 30 damage attack
an attack that absorbs a base of 20.
 
No here are the reasons golbat is better
 
better retreat
a stage 1
no pokemon resistance to grass.
less enrgy requirements
 
The only reason I can think of that makes Kabutops better is absorb does more damage than Golbat.
Many pokemon are weak to fighting but many are resistance to it too. Unless your opone t has a defender or a porygon you heal 20 and 40 if weakness per turn. Kabutops is like base gastly, no its worse.
 
So in conclusion Kabutops is actually useless, unless you go buy 5 fossil packs and all you get are kabutops.
