There is a huge difference in blade quality in terms of cut quality, sharpness of teeth, the ability to sharpen a blade, stiffness, etc. many people here use Freud blades, which can be very good. I just purchased the Freud glue line ripping blade, and it does a fantastic job and leaves an incredibly smooth cut. I also use a forest WW2 combo blade and it also does a very nice job.
What kind of saw do you have, jobsite, contractor, or cabinet type? What materials do you cut? The Diablo in the first link is a thin kerf blade which works well for saws that can run on 110v, or lower power saws since it removes less material it requires less power to run. Good blade, really don't think you'd be disappointed. The Fusion is a top line full thickness kerf and plate blade and should really be used in a 3hp saw, but would work well in a lighter duty saw on materials and cuts appropriate to that combination.
Here's the thin kerf version of the Fusion:Other than tooth count, what's the difference between these?

Yes. MDF is easy to get a smooth cut in, but is very abrasive, and a triple chip grind has excellent edge life. The LU82 is an excellent choice for MDF, though it won't crosscut as cleanly in some materials as an ATB or Hi-ATB grind.Okay, now I've read most of your blog and I looked over the blade list. You didn't have a 10" TCG listed, should this be decent? (For MDF.)
