Can someone provide a good alternative to MS Project 2013.
I find this to be a dangerous question. All tools have various levels of functionality and capability and its set of quirks or weaknesses, all with varying price points. Seems to me your "best" is one that meets your current set of requirements the best at a price you currently can afford. I think the answer will change for every new project you jump on to some degree. I think trying to find an answer for a best will bias you from making a reasonably objective analysis of tool fit in your future.
Personally, I remain tool agnostic. If it meets my current requirements and I can afford it, it's the best...for right now.
