I just ordered the first book, and I'm currently watching the series so I should be able to give a good opinion in a while.
I am reading Legend of the Galactic Heroes Vol. 1 at the moment, it's pretty good and has been living up to the hype so far. Much more serious fare and well written too. Translation is quite good as well, flows nicely.
Really? I find the sentence-structure strange/clumsy (and their length to short), not flowing well.
I actually looked this thread up to ask, as surely some people here have read the original,
if that is an effect of directly translating japanese text-structure, or if it's because of the original writers writingstyle,
because in comparision, afair, Guin Saga was much nicer languagewise with a good flow (at least the english translation).
there is a discussion in the light novel thread as well.
