The one on the left is my first Hi-ATB blade (it's also my first variable pitch blade). It has 80 teeth.
The one on the right is my first rip blade.
They're both 1/8" full kerf, the left one is 10" and the rip blade is 12".
Total cost was about $50 including shipping and having the 12" blade professionally bushed down to 5/8".
Between these and the recent 9" Delta 35-7656, I will have no excuses other than operator error for poor cut quality.
