Executive MBA (E-MBA) with Manipal University or Executive Post Graduate Program from Alliance Business School?
Alliance would be my bet, simply because of the brand it is. It is recognized as one of the renowned Institutes in Bangalore. Sikkim Manipal is mainly known for its distance learning education. The best executive MBA degree providers are IIMs. ICFAI, Symbiosys and other Institutes provide executive MBA degree as well.
It is not clear from your question whether you are a working professional, student or an employee of IBM. Executive MBA programs are normally cannot be used for a career change in India until and unless they are full-time programs for which you have to spend an year or so out of work. IBM might have a corporate tie-up with some University so that its employees can pursue higher education but this could exclusively be for its present employees. Check at IBM India website or if you are employee of IBM, check with the HR Manager. But if you are eligible for E-MBA then the best option would be the programs offered by IIMs for which you have to write GMAT. IIM’s E-MBA programs are full-time one-year residential programs after which you also get to attend campus placements.
