Depends on your goals in the game.

If you do not want 100% completion and not have the attitude that skipping is the easy way out : do not upgrade. You can use the non-spent 102 on other topics. (at least save yourself 5 hours of farming)

Else : upgrade so you can finalize EXOS experience to 100%.
