That is, if I can catch a Pokemon with a CP of 1850, but then I checked the IV and perfection, and its perfection can be any where from 55% to 76%.
Now, if I have another Pokemon with a perfection level of 97.8%, and I spent time powering it up, but so far its CP is only 1850, the same as the other Pokemon.
Now, these two Pokemons have the same CP but different IV and perfection. If I let them stay at a gym, do they have the same amount of chance of winning in general due to the same CP, or is it hard to say?
In some situation, if I catch a Pokemon with CP of 1950 but perfection of only 60%, then I wonder if I should let it stay at the gym or let my Pokemon with CP 1850 and perfection 97.8% stay at the gym.

IVs are included in the CP amalgamate. In general, two Pokemon with the same moveset and species will be roughly equivalent if they also have the same CP; if one of them has greater IVs, then the other will undoubtedly have a higher level.
There is some variance because the CP formula values Attack quadratically more than Defense or Stamina, even though their respective effect in battle is proportional (with Stamina contributing slightly more due to the fact that it also serves as a reservoir of Energy). Thus, Pokemon with higher Attack will be over-rated, and those with lower attack will be under-rated. IVs will, naturally, contribute to these proportions.
