To put it the opposite way, whenever I am in a "big bet" table, I am tilted by players agonizing whether to open for 6 or 8, or tanking everytime they gave a bet.
In limit these decisions are much quicker. Meaning more hands per hour, which means more meaningful decisions per hour, which is better for better players.
In "big bet" games, I do understand a fewer chips may make sense because stacks have to be counted frequently, as I said above. (But I also think there are diminishing returns of you are using too many denominations.)
In limit games there is never a reason to count a stack unless the stack is smaller than a bet, that's the only time a player is all in at limit, so that's why large quantities of chips in uniform denomination make sense in limit.
And besides, plenty of room on this table.
