Had both
Threw the wok in the load of scrap steel going to recycle.
The plow disk is by far the best, it holds the heat, distributes it well, won't fall off the cajun burner. After you cook the onions, peppers and meat, you can set it off to the side to keep it warm, and toast the burrito wrappers in the middle. I sanded mine a couple of times with an angle grinder to smooth it out, mine was a new one.
I use an old milk crate with Gastobac burner (used in the tobacco barn for curing cigar leaf); they are not easy to find if you're not in tobacco county. It works better than a cajun burner!
If you need and endorsement - go for a plow disk, and if you don't like it I'll buy it from you!
