While I can't speak to the internet hive mind, there are a lot of curved blades I really like. The khopesh is my current obsession as I wonder if it can be scaled up in size thanks to modern materials. Also, I dig the falcata and twin hooks, although the later may require a level of coordination I don't have.
With that said, the bat'leth has always struck me as a rather silly weapon, for a lot of the reasons the video goes into. While I don't know how I feel about Shad's version of it, outlined in the video, watching Trek, it always struck me as being awkward to use. While it doesn't say it, the video illustrates how it is over-engineered, reducing it's potential effectiveness.
