Katanas. Do they worth it?

Well, title says it all. I wanted to start a Blade with katanas for RP, but now I'm swaying towards F/M with Scimitars... Or long swords, since they are just so much better (This discussion is NOT about Blade vs. F/M!). Probably take one pip in BG2 for Celestial Fury.

So katanas... How I see them:
PROs:
1. They are badass cool.
2. d10 dmg for one hand.
3. Pretty good speed factor (but not that much)
4. Celestial Fury.

CONs:
1. Rare. By the time you get a decent one, you are already able to choose from many badass long swords.
2. Have lower THAC0 bonuses than most other weapons in the same game (this also goes for bastard swords in BGEE, but at least we have some different +1 ones with some minor bonuses)
3. In BGEE there's only one katana +1, so no dual wielding.
4. Best katana in BG series (Hindo's Doom) is only +4 even when upgraded, and it get's it's ass kicked by Spectral Brand, Angurvadal, Foebane, Purifier, Flail of Ages and almost all the other top weapons.
5. Apart from Celestial Fury (and Dak'kon's Zerth Blade if you are a bard or F/M) no cool bonuses.
6. Oh, and you can't buy a katana from your starting money in Candlekeep.

So, what do you guys think?
