Something from the polearm line, preferably a Glaive, Partisan, Fauchard, or Corseque.
Or perhaps something I can dual-wield. Perhaps Xiphos/Makhaira, Spatha, Katzbalger, Any kind of Dao Sword, etc. I know some of them may not be preferable to dual wield, but as long as they're one-handed, or a "light" two-handed, I'd try to learn how to dual wield them effectively.
I also don't see what's so amazing about a lightsaber. Sure it's powerful, but all it is is a glowing stick. It technically has no blade, no defining edge, it's a glorified futuristic, multi-colored club that can tear through people.
