I use 5 rods primarily; 3 baitcast, and 2 spinning. Of those I have 1 spinning rod purposely with micro-guides and two casting rods purposely without. The other 2 rods don't have them, but that was more by chance than design (meaning the type of guides didn't play into my purchase).
My personal criteria: leader needed = standard, fishing "junk water" = standard, light tackle = micro
Your mileage may vary.
