DSE, Hotchkis, or Hellwig sway bar for stock subframe?

[BBC71Nova]

Getting ready to work on my subframe and want to go ahead and pick up a sway bar to mock up with. Is DSE and Hotchkis the same bar with a different label or are they actually different? They seem similarly priced. Don't know much about Hellwig but I see them mentioned often on forums. Thoughts on which is better? pros vs. cons?

I've just got a stock subframe with Speedtech upper, lowers, and QA1 coilover conversion. Car is '71 Nova with a big block.
