I believe this is because 6063 is rarely available with a strong temper/heat treatment. I have had the displeasure of post-weld machining 6061 with even worse results because it has nearly been annealed. 3003 and 1100 are also garbage to machine for the same reason I think.
Extra strong alloys, like 2024 and especially 7075, machine like butter in my experience.
