You should try to talk to and collaborate with your team members, Javed Khan and Sidrah Shah...
Next, you're comparing a query language with a rule engine - those are obviously different things (although you can do some things also in SPARQL that you can do with Jena rules.) Regarding performance, there is no answer. Obviously in Jena both is executed in Java probably using some shared Jena core functionalities. Nevertheless, there is no need for comparison. The question that comes up here in the mailing list - why are you still asking those basic questions? What is the task of the project? I remember that you used Jena rules all the time - now you're think about using SPARQL? Why? Inferencing and querying are totally different things. So why are you thinking about refactoring the whole project? How much time do you need for this academic project? I mean, it sounds like you're working on it for almost one year now? Is this really necessary and useful to spend so much time on it?
