Can you give some context of what the board is for? This thread is a whopper.
Personally, if you have £200 to spend on an AM4 motherboard you should probably be looking at AM5 instead.
I wouldn't want to spend much more than £100, but does something like the Gigabyte B550 Gaming X have sufficient features for you?
The Strix -F, Tuf B550-Plus, Tomahawk and Aorus Elite are all higher tier boards, but if you don't need the features (e.g. a beefier VRM, 2.5 Gb LAN, higher-end sound, SPDIF) there's not much point.
