Great topic Pottzy!  I am a Diablo guy.   I have 6 that I use for the Saw Stop.  All different tooth count and sizes, from 6 1/2 to 12.  I have diamond blades for the tile saw, and 4 1/2(?)for the small cordless Ryobi.   I do not sharpen them any more....I throw them and get new.  Sharpening around here, does not pay. 
I have Bosch hollow ground blades for my hand jig saw and Lennox for my recip saw....except I do have some Dialbo recip blades for for tree limbs or destructing.  It is super aggressive.
