Pricey, but safer.
You will get superior abrasion resistance. A higher temperature rating I believe.
A twist lock connector would prevent the possibility for the cable to come out accidently.
I'd also reccomend the L6-20R receptical and matching plug L6-20P.
The ends must be properly strained reliefed. A portble cord connector is essential. If it's subjected to a lot of pulling, you can get a wire mesh like strain relief. The harder you pull, the tighter it gets. Something ... the correct size.
That would be by "suggestion" for the best method. It will be pricey.
Some might call it overkill....
