I like the symmetry of 15, 14, 13, 12, 11, 10.
But it is moreorless the same thing.
It doesnt really matter what the array is, since everyone will be using the same array.
An advantage of using lower numbers is accommodating bounded accuracy.
And some people really don't like having many odd numbers. And some want there to be one weak stat. Some people like being able to represent a prodigy at low levels, being able to have an 18 at level 1.
If there was a stat cap of 18, the following could make all of them happy, and reduce the need for ASIs later on:
16
14
13
12
10
9
That is equivalent to a 31 point buy (if the 16 counts as 3 points). Below are some examples of what can be accomplished using the +2/+1 background ASIs.
Character 1, the Prodigy: The 16 could be bumped up to an 18 if they really wanted. The remaining +1 could shore up the 9 to a 10, or the 13 to a 14. This could end up with a 18, 14, 14, 12, 10, 9. Every ABI going forward would shore up secondary stats, if that was important to the build. Otherwise the player could focus on feats that expanded their function.
Character 2, the Well-Rounded Expert: The 14 and 13 could be bumped up to 16 and 14 respectively, for a 16, 16, 14, 12, 10, 9. This is a solid build that helps MAD characters.
Character 3, The Jack of All Trades: The 13 and 12 can be bumped up to 14 and 14, resulting in a 16, 14, 14, 14, 10, 9.
Character 4, The Better than Average Joe: The 12 and the 9 can be bumped up, resulting in a 16, 14, 14, 13, 10, 10 and would have no penalties. The 13 can be used to qualify for Heavy weapons, or multiclass, or just be bumped up easier in the future.
