I've used Socialise v2 now on Jomsocial Pro v4.1.1 Joomla v.3.4.4.
The template settings for the mega theme editor could be allot more informative on the popup descriptions, (a problem across the whole JS range) where the popup simply parrots the option title. (USELESS) So unless you're in the development team and have a good working knowledge of the respective UI options, JS fails miserably to inform the administrator about the option parameters.
The Socialise v2 English language files require quite a few spelling and punctuation corrections, so as not to look unprofessional on your site's front end SomSocial UI language constants.
On a positive note however I have to admit that if you're starting out in the JS social community website development, you could do allot worse than using JomSocial. the core as of v4.1.1 is remarkably stable and performs well on my budget server array.
Support is slow and communications can become crossed because of the inherent lack of live support (an essential part of any busy support website).
Conclusion: I like and promote both JomSocial and Socialise v2, but there are areas of the service that could be improved for both the customer and efficiency of the support infrastructure.
