Jtrial

get the aorus if its within your budget.  There were some issues the the tomahawk but im not sure if they have been fixed

how much are you willing to spend on a motherboard?  What currency are you using?  Do you plan on overclocking?  does the mobo need to be a certant size?

pretty sure that x370 board wont work with 3rd gen ryzen.  you would need at least a x470 board but i would probaly go with the aours pro as they generally tend to have the best vrms

Both the prime pro and tomahawk are solid picks
