I have both Crunchyroll and Funimation account... but while Crunchyroll is more expensive - their service has been quite consistent. Funimation, on the other hand - has some nice dubbed ones etc - but not liking the services.
I have PS3 downstairs for some media playing and PS1/2/3 gaming purpose - but Funimation app doesn't even open up, while Crunchyroll works just fine. On PS4, both work pretty well -but I think they just dropped PS3 support all together.
Even on Roku - when I run Funimation - I have trouble switching English voice and Japanese voice - I have to try switching a few times and it barely works. On the other hand, Crunchyroll seem to work just fine.
I had the subscription for Funimation for some exclusive ones for my daughter (Black butler?) - but I think I will probably drop it sooner or later. A lot of things that I'm interested are already available on Crunchyroll + hulu + netflix + amazon prime services that I have...
