In the position Gilchrist bats, it is ALWAYS the best for his team to bat in that manner.
If his team has collapsed, a Gilchrist innings will not only bring back the match, but him doing it fast enough makes it possible for Australia to squeeze out a good innings total. If his team has dominated and he comes in, the faster he scores with the remaining balls, the more devastating the total will be. Gilchrist, in his position, should never really play that kind of innings. It would be a very rare game to see Australia 50/6.
And to be honest, I've seen plenty of gritty Gilchrist innings that showed the same resiliance as a Dravid - he just happened to do it a bit faster. Can't pop up at the top of my head, and I can't look it up because I gotta go, but I am sure others can put in an example or two.
And before a few people pop-off green and gold bias, Dravid is one of my favourite batsmen ever.
ADD: You said specifically 'consistently', well I can't answer you honestly. Not that I don't think he can't do it, but as aforementioned, his team is rarely in that position to begin with for him to have to do that.
