I like that it has so many different features, from blogs all kinds (including blogging) right up to forums without any hassle at all! When we first used this system there was an issue with some plugins which were causing problems but they have since sorted those out - everything works perfectly now as per usual in our experience using them previously too :) There are no downsides really other than having lots more options available if one wanted additional functionality etc then perhaps its slightly overkill? We use bizzcom mainly because although wordpress does offer much better support overall including automatic updates/security patches; however their documentation can be somewhat difficult or confusing where ours just makes things very simple :). I like that it has so many features, from different templates all with their own functions (like blog posts), as well as page layouts which are customizable! There isn't much out there in terms or functionality but this one does what we need very nicely!! So far nothing negative at least not anything i can think about right now. We use bizzcom mainly because its been around awhile without any major issues being reported by others who have used other products such us wordpress etc..
