I would rather go with sonm project I was in GNT but they can't deliver their deadlines. Sonm there PR is shit ass hell but they do get the job done and are rapidly expanding their team so I expect alot better PR soon (see their last monthly update)
I also think Sonm is a good bet long term. A very under rated coin due to the lack of hype which stems, as you say, from their poor PR.
I definitely prefer this over Golem.
