@KRC2013 it really depends what your Digital Signage needs are; features, support, warranties.
The benefit of Mediasignage is the low cost of entry/monthly costs, however unless you are in the US it's worth considering the support you require and the potential size of your digital signage network. Based outside of the US it is almost solely via live chat (which is pretty good I must say) or email. If you're sourcing hardware (players) then from my experience and from reading the forum, the most stable players are those supplied by Mediasignage - which only ship from the US, so bear in mind freight time, import taxes (and returns of faulty hardware in rare instances) etc.
Sorry I've not really given you an answer, but a few paths to consider when you're evaluating what DS platform to choose.
