You should not look at path as balanced choices, but rather a further difficulty adjustment with flavors.
This is a good way to look at it, I think. You're basically picking whatever your 'main' unit is going to be. Gals Are Superior makes your battlescape gameplay easier with tougher and stronger units (because Gals
really are superior) but you're inherently going to be running smaller squads and you might struggle to pay for them once you've got a lot of high rank troops. Peasant Revolution and Male Touch both let you hire lots of rookies, with Peasant Revolution focusing heavily on bulking out your roster with mid-tier units and lots of training. The baseline humans are slow, fragile, and weak compared to Gals but they're also much cheaper, much easier to replace, and quickly unlock large squads with the Trucks/Harvester transports.
You can get Young Ubers and Castaway Gals from occasional missions and events, things like the brothel raid or landed necropirates, so you aren't completely locked out of them without Gals Are Superior. If you're happy with occasionally harvesting Gal recruits from the map and you're not losing too many of them to medbay or death then you can totally rock the Peasant Revolution and get some high-grade meatshields.
