Drysuit threads are very common on SB. Look at this one:
http://www.scubaboard.com/forums/basic-scuba-discussions/354287-what-drysuit-would-you-choose.html especially Thalassamania's comments.
Thal's synopsis: once someone has sunk lots of $$$ into a drysuit, don't expect them to post anything other than "I have an XXXXXX suit and I love it."
That being said, I have a DUI TLS 350 and I really like it.
Nevertheless, as Thal points out, I have a limited diving history and have only ever worn the one suit. Even on SB you will have a hard time finding someone who has gone through several different suits.
Try them both out. See which you like.
From what I have read on SB, those who like the Fusions REALLY like them. Anything which is a drysuit and can claim to dive like a wetsuit sounds like a winner to me.
From what I have read on SB, those who don't like the Fusions REALLY can't make them work for them - be it body proportions, or whatever, some just can't make the suit work for them.
Finally, if you are independently wealthy (not me) or hooked on diving (me) you can opt for a custom-tailored suit - I did. TSandM has heard of horror stories with this approach (you should PM her), but my experience was very positive, but costly.
