I use the regular.
Before the Halo, on hot humid rides I would often have stinging sweat in my eyes. The Halo solved it for me. I know some BF posters have said it does not work for them (maybe their sweat output is too high) and if that happens Plan B is the Sweat Gutr. But the Gutr has a hard piece of plastic as a channel which I suspect is uncomfortable, while the Halo uses soft comfortable silicone.
