The GSkill reference you listed (F4-3600C16D-16GTZNC) is on the QVL as well from ASUS for this RAM as on the GSKILL list for this motherboard. Which is a good thing.
For the Corsair kit, what reference exactly ? There are a lot of different 2 x 8 Go CORSAIR VENGEANCE RGB PRO kits, with different speed and CL.
You noticed that on the QVL at Asus
https://rog.asus.com/motherboards/rog-strix/rog-strix-b550-f-gaming-wi-fi-model/helpdesk_qvl_memory
the fastest Corsair 3600 MHz kit are with a CL of 18, yes ?
Also, there has been quite a few reports on this forum with Corsair RAM in conjunction with Ryzen CPUs not working at maximal published speed.
Frankly, between the 2 you proposed, I would go with Gskill.
