I have to say. Platform 5 from PageLines is really promising. After just playing around with it for an hour or two on christoph.no I am actually very close to purchase the pro lisence. Just to get a hold of that Loops extention.
Although I’ve only given it a test-run with the trusty old twenty-fifteen theme I am pretty sure this thing has a great potential for producing simple state of the art webpages for the lower tier segment.
