Cat lll vent pipe brands?

[CJseven]

I’m fixing to hook up a mr heater 80,000 btu in my shop, I looked at the saf-t brand at Menards , about the only brand I have access to locally. It has tabs that when slid together you bend over to hold it, the other brands I have seen online all seem to have band clamps. Is there any advantage from one over the other brands or are they all about the same.

Cat 3 flue has to have a UL rating so it shouldn't matter

I would avoid any brand that requires silcone sealant at every joint as well as any brand that you can't cut down the length. I'm not a huge fan of the 3 tab fold over deal to connect but it's not the end of the world, I feel that the stuff with a clamp simply looks better.
