In fact geometry is more important and as dawg was saying, task specific.

As a 31 year carpenter I can count on one hand where I've needed more than 24 teeth, on a circular saw. Too many teeth cause too much heat for most lumber.

Heat is what dulls a carbide blade. Heat breaks down the cobalt that holds the particles of carbide together.
Here's some of the basics, when it comes to blades.
Very helpful, thanks!
For my general purpose cutting needs, how do you feel about the thin kerf on the 24T Dewalts, I linked to earlier?

Other than general purpose cutting, I have the following projects and/or goals:
1) Repair & replace sections of wooden bench, fencing and gates.
2) Remove & repair section of 3/4 plywood subfloor under 2nd floor toilet.
3) Flooring: install baseboards, scrape adhesive from plywood subfloor, under cut door threshold trim.
4) Refinish oak staircase and rails.
5) Begin to learn basic woodworking/DIY Furniture building i.e. Adirondack chairs, wooden benches, bookcases/shelving, cabinets/doors, etc. FWIW, I'm saving up for a table saw, router and clamps.
I like your plan and the blade you linked in your original post will work just fine for portable saw projects. Save the fine furniture building until you get your tools you're saving for.

For your portable saw use, I recommend building a saw guide(s)to accompany it. I have one each, 4 ft. and 8 ft., for 4x8 sheets and another for cross cutting 2x4s - 2x8s and occasional 2x12 etc. Once you are accustomed to those the speed square will draw dust hanging on the peg board.

I can't say enough good things about Diablo blades. I picked up a bunch for my circular saws when they had a buy one get one free sale a while back. Now I want to get some for my miter and table saws, although they're a bit more expensive for the 10"

Cool...Now, that said...To me, it seems like a no brainer but without seeing/using the blades, I have to ask...If you were saving for the future, like I am, and had $10, which would you buy?

A) Single Diablo 7-1/4 in. x 24-Teeth Tracking Point Framing Saw Blade
B) The 2-pack Dewalt 7-1/4in Saw Blade (DW3578D2), I linked to in op.
C) This 5-pack Hitachi Circular Saw Blade Set (115402).

Thanks!
I like that idea...Too bad, I just tossed the scraps from an old bathroom cabinet, I just demoed.
