Honestly safari tours in India are not that great. They certainly are not bad, I've enjoyed them and I would recommend them. However there are so many things to do in India that are far more interesting than going on a Safari tour. If you're really interested in animals and birds then go for it, but be warned that you are not going to see many. Africa is far better for animal safaris, on an Indian holiday I would recommend visiting historic sites and beaches or mountains rather than safari tours. If you are really interested it than go for it, otherwise It'd be wiser to make other plans.
