Perfect Mika has a Soldier Count of 21539 whereas the "worst" Mika made with two UR drops has 21111. The difference is very, very low and the gap might widen just a bit more once the event is over and you upgrade her with the Ranked Reward.

Personally, in my year of playing this game I may have had one or two fights in total where I was glad or wishing I had ~500 soldiers more. Usually battles are a lot mor decisive, so whether you want to go for a perfect one comes ultimately down to if you think those 500ish soldiers are worth the Slimes spent on the rares. Like my poster above, I'll go with 1 perfect for Idol Mika and keep the rest of them mixed.

As a reminder tho, don't just throw away your R Mikas, remember that two of them are worth 2000 Medals if you just amal them even without leveling up.
