Saw Blades on Stucco

While training at the 51st apartments we wanted to compare our saw blades on stucco.  The first cut is using the "nugget blade"(random carbide tipped) and the second is using a diamond blade.  You will see that the diamond blade did a much better job on the stucco.  The nugget blade was an old blade but it seems like the diamond blade was still a better option.  Stucco which is similiar to concrete was very abrasive on the saw blade.

Review the previous post, Choosing the Right Saw Blade for the Job.

Has any anyone had different or similiar experiences?
