I've used a baron, and jr. gent, and ligero, all seem comparable to me. I prefer the smaller nibs on the Jrs. though.
However, I'd definitely suggest getting upgraded nibs from Lou. They definitely write better! I write very small and for me a medium pt. FP just didn't work. I was able to get extra fine SF nibs from Lou and they write like a dream!
You may also want to get better ink. I've been told that the ink that comes with them is junk. I also purchased some Private Reserve ink from Lou and it writes very nicely. Comes in lots of colors too...
Enjoy!
