3200mhz ram vs 3600mhz ram

Hi guys, so recently I’ve saved up enough money to finally build my own pc with a ryzen 5 5600 and an rx 6600 which will be an upgrade from my old laptop which is running an intel i5 10210u with integrated graphics. However I have no idea whether I should get 32gb(2x16) of 3200mhz or 3600mhz ram, please help, thank you.
