Fair enough, and I understand the importance. Gilchrist is the fastest batsman in modern Test history (by all accounts he is almost/just as fast as Viv though they didn't measure SR back then), and Lara when on song is up there too, and while I appreciate the effect of innings such as his, and realize that they could demoralize bowlers, I would still take someone who scores appreciatively more, even if it is at a slower pace in my Test side.
Of course, in his prime he scored as much as anyone and did it very destructively too, so thats why I rate him as one of the best of all time (top ten). But my estimation of him would not go down (top ten easily, top five maybe) if he had scored much slower (or as swervy put it, in a different manner which leads to a lower S/R). Maybe yours would and that's fair enough, but I still maintain that runs scored is the primary focus, the method of scoring is a secondary criteria.
If you think he would still be second to Bradman if he scored a little differently, then I accept it as there is usually very little to separate #2 from #10 or so in an all time list. But my point earlier, and it is one which I still stand by, is that from my experience people rate him higher than they would primarily because he scored fast and thus had that aura, hence my terming him 'overrated'.
