help with picking a keyboard

Hi I am looking into getting a razer keyboard I all ready have a mouse and a mouse pad but I can’t decide what keyboard the keyboard I’m looking at is the Blackwidow v4 pro full keyboard or the huntsman v3 pro full keyboard I do play a lot of shooters games and racing games I just can’t figure out what one to get and I’m coming from using a Corsair K100 right now I also just got Razer Firefly V2 Pro and Razer Basilisk V3 Pro
