In My Humble Opinion, no two answers will be alike.
I go mostly by width and thickness..IE: .026 x .011
I do believe that I could buy nothing but a selection of .026 x .011 blades and I could cut any pattern with them.
There are a variety of these .026 x .011 blades, reverse teeth, skip tooth and a variety of teeth per inch.
I use .022 x .008, to .034 x .015
Blades # 2, 3, 4, 5's each come in different width and thickness
I suggest you get a couple blades in the .026 x .011 ... one .024 x .011 one .029 x .0?? and one .032 x .0??
