Hello Subha jit,
Both courses are good but only if you pursue from good college. If you pursue MBA HR from any good college, then your package will be good. That is also true for another course as well. So main thing must be focus on good college. Scope in MBA HR is larger because MHA college are not that much as well as college equipped with good Infrastructure. You can find lots of good college for MBA HR.
Good Luck

MHA is niche and has lessser job opportunities as Hospitality sector not known for Payscale and also finds limited management opportunities  

HR has vast expertise in various facets and roles and also good paymaster comparatively. Moroever, with good experience and from good Bschools you can attract better remuneration.
