The platform itself isn't really anything special -- it's just another free site that allows you post links (that are then distributed by third parties).
I wouldn’t say this was my favorite PR tool — but we were using other ones as well at about equal cost/benefits so didn‘ think much one way or ttheother when making our decision here either! That said though - they have recently made some significant changes with regards user experience which has improved things considerably since launch in May of 2016.
