Right now the plugin in free version has less features than lazyblocks.com e.g. repeater fields, term select included, import export blocks. For me lazyblocks is more developer friendly and flexibel as i offers code in templating using php or html handlebars, with a good documentation and some usefull actions and filters.
Also the easy to add features if you have installed ghostkit like Spacings, Display, Animate on Scroll, Frame, Custom CSS are very helpful.
