Mr. Jim, to truthfully answer your question is near impossible here because you didn't give us the type & thickness of your material you're using, & what type of work you are planning to do with given blades. Speaking for myself, I use FD & Olson blades, & keep about 20 different types & sizes of blades on hand from skip tooth to scroll reverse, & #0 - #7. I do quite a bit highly intricate projects, & my personal preference is a #2 skip tooth, or a #3 polar blade. For extremely fine work, I use a #1 skip tooth. For certain things in projects, I also use spiral blades. Sometimes it may be a #1, other times it may be a #3. I don't spend much time finish sanding, the saw does the work. An important point to keep in mind when looking at different projects, is to keep your blade inventory in mind. Every project may take 2, 3, sometimes 4 different types of blades, & at least a couple different sizes. Also take into consideration your material. The thinner the material, the smaller the blade, & the slower the speed. The thicker the material, the bigger the blade, more blade speed, & more blade tension. There are several variables that enter into the decision of blade choice. The only true way is purchase a dozen of a few you'd like to try, & practice. Good luck!
