Trying to find the best ram for Ryzen 1500x build

[throwaway14242555252]

Having difficulty figuring out which the best ram I should get for my ryzen 1500x build. Looking for it to be 8gb and budget friendly. Around $100 im looking for it to be, nothing to crazy expensive. looking for it to be part of either the MSI B350 TOMAHAWK board or ASUS PRIME B350-PLUS which I also haven't decided my mind on which board to get.

Decide on MB first. Processor doesn't care which RAM you use as long as it's DDR4.
