Shorties vs. Soakers - please read before voting

[Tiny Trousers]

I prefer longies but for summertime Texas weather I need to do soakers or shorties. My ds will only be 5 months this summer, if that makes a difference. I am asking because I want to knit as much as possible before my newbie arrives

So which would you recommend for a little baby boy in the summertime? We use pul covers when out.
