I personally prefer to play AND DM a variant human than a regular human.
The regular human benefits from odd numbers, but how many they can get.
The standard array of course doesn't favour them as it only has two odd numbers.
The relative value of being a standard human with rolled ability scores can end up very good (if you roll lots of odd numbers) or very bad (if you roll mostly even numbers)
But with points buy and the standard human you can have:
16, 16, 14, 12, 10, 10 (+9 total)
16, 14, 14, 14, 12, 9 (+9 total)
16, 14, 13, 12, 12, 12 (+9 total)
16, 16, 16, 9, 9, 9 (+6 total )
Which I think is kinda awkward for what is meant to be the simplest character choice.
It is both the least mechanically interesting option, but also rewards system knowledge.
