Smile [Q] About CWM 11 on i8160

So i am planning to install cwm 11 for the kitkat features and stuff , I am going from 2.3.6 to 4.1.2 (XXMF2 Which is really really laggy on my device) to cwm11 .

My question is : Is cwm11 better and more optimized than the laggy 4.1.2 stock and is it worth it to a legacy device such as galaxy ace 2 to install it ?
