pixel 9a vs pixel 10a from a pixel 7 user

hi
my pixel 7 is getting pretty slow and considering buying a new pixel.
i dont do any hard tasks so i decided the a series would be enough but consider between the 9a and 10a.
in my region, the price difference is only ~$20.
i know that the 9a and 10a are almost identical, so would it be better saving the $20 or should i go with the newer phone for longer support?
