2h is better. A 2h sword is just better than a 1h sword. And the argument to not use a torch and 2h weapon at the same isn't arbitrary or gamey. It's a 2h weapon by definition. The argument for special rules for 2h swords vs the rest could be made, but BM said they don't want special rules for certain 2h weapons, and the pole-axe cannot be managed without 2h.
