What Zapdos is good for apart from the obvious?

Pidgeot with any
Dragonite with SW and/or Hurricane
Crobat with any
Lugia with any
Ho-oh with any

I just never did anything with Jolteon nor Flareon. I was always playing catchup for the old gym system and they wouldn't get me high up one. Plus these legendary birds have higher IVs than my top eevee evolutions***If you have considerable rare candy, worth powering. I'm storing a bunch in them already and have 120 more taking up bag space
