I went to blaze pizza 4 or 5 years ago when it first opened up in Irvine, CA. I remember they used to limit the amount of toppings you could put on your pizza which was a huge drawback. In addition, I don't remember anything memorable from that experience. After that one time, I always went to pieology.
I was looking for a pieology in the henderson area after moving out here, but they didn't seem to have any around. I opted to try Blaze again after a mediocre experience waaaay back and was pleasantly surprised at how much better it got.
The original sauce that they use has a tangy flavor which is nice. I don't think pieology's tomato sauce was quite as good. It was also nice to find out that they don't limit the amount of toppings for a build your own pizza. All in all, the toppings were pretty fresh and the pizza turned out great. I would say the pizza turned out slightly better than pieology's.
I will be back again soon!
