In my experience all of these so called "Professional" torches are worthless due to the relatively small output. You'll spend minutes caramelizing each brulee.
I'd stick with the Benzomatic. Just make sure you're using it over a heat proof surface. I lay a sheet pan over our steel sink and brulee on it.
I also use the torch to char the skins of peppers to easily remove them.
