0.75 has less issues than the others, and a lot of improved features - it automatically checks other users share lists and downloads from them if they have the same file (much like torrents, the one file can come from many sources)
0.306 is the old version that doesnt require hashing, but lacks all the awesome features (and tends to bog down a machine more - it seems to hash when files are requested, making it harder to run while gaming)
my advice is to use 0.75 or 0.674 0 or a combination of both. (i share in 0.75, and download via 0.674)
there is no valid reason to use 0.306 other than pure laziness. Takes too long to hash? tough. you only have to do it ONCE.
