Er, first of all Tendulkar, Dravid and Laxman themselves are not in the same league.
Here's my ranking of Indian batting greats (from those I have seen in action, so excludes old-timers):
Tier 1 (world-class ATGs): Gavaskar, Tendulkar, Dravid
Tier 2 (Indian greats): Vishy, Laxman, Kohli (has a chance to move up in the category above), Sehwag
Tier 3 (good batsmen): Vengsarkar, Mohinder Amarnath (a shame he couldn't make it to tier 2, but he was quite inconsistent), Ganguly, Azhar, Gambhir, Pujara (will definitely move to tier 2 by the time he's done) + I'm sure I'm missing a few more
