When looking for a blowtorch for the kitchen, you can buy some reasonably expensive tools. When looking for a blowtorch for plumbing, you can buy some reasonably cheap tools.
The price is different. The look is different. The principle is the same. I guess the gas is the same.
Why pay more? Is there a health issue? Is the kitchen blowtorch more precise?

Yes, there is no real difference.
Be aware that if you one from the hardware store, it should be one where the flame does not fluctuate when you tilt the torch. This usually happens with the very cheap ones. This becomes a big problem when you try to uniformly brown something.
Aside from that and maybe "esthetically" I see no reason not to use one from the hardware store.
