it absolutely matters. because you're rolling more dice for 8d6, it results in a wider spread of values since the min is lower and the total number of different outcomes is more. with 6d8, which has a peakier curve, you're more likely to get a result somewhere around the median. think about it this way: if you could choose to roll 24d2, or 2d24, which would you prefer to roll? both maximums are the same but the distribution is very different
