I'd get the dot info domain. They have recently began to show up a LOT more in the serps since Google's shit back in late 2013 through 2014.
Anything with hyphens may not hurt you SERP wise, but a more memorable domain will always help those that want to come back that do not bookmark.
Use the dot info... that's my opine. Hyphens confuse people for the most part. Remember, society as a whole is pretty dumb. They like simple shit.
