You are free to downlead whichever you want to choose.
The first one, the one done by Fujino has a few mistakes and is somewhat incomprehensible during a few moments, but overall is quite solid.
On the other hand, the Seikei translation has a much better quality, even through it isn't perfect. The downside is that it has new names for all characters (except the originals) to avoid a copyright claim.
If characters having different names isn't a deal breaker to you, go with Seikei. I personally played both of them, and probably enjoyed the original machine translation more, but other people might have different preferences.
