Social Activity Like and Comment features

Hi I am using KLEO COMMUNITY THEME it relies on Buddypress for creating its basic and core functionality,

But my website does need features like Social Activity and Social Login to make it functional and look attractive :),

I do need some clarification before making the purchase of these two plugins?

I am ready to leave BuddyPress If I am provided with a suitable alternate.

Please do reply ASAP.

Respect and Regards
