Especially if you want to go mini-ITX! The B450 ones are £120 to £160,and seem worse specced than the B360 ones,and the B350 series ones will be quite variable on whether you can get out of the box support.
It seems companies making higher end AM4 boards seem to be quietly adding a premium to them compared to the Intel ones. One company which didn't do that was Biostar - their X470 mini-ITX board was £100ish and even had optical out too,but it seems Ebuyer does not sell it anymore,but in the US you can still get it.
So I am looking at the Asus ROG B450 board as I want a top mounted M2 slot,and the B360 one is just better specced(even has optical out and a much better rear panel) and costs £30 less:

The cheaper Gigabyte one has very poor VRM temperatures,and the ASRock B450 one has a 3+3+2 phase VRM which probably is fine for the Ryzen 5 2600 I am getting,but I am uncertain longterm how it will be if I choose a higher TDP CPU,and its a £120 to £130 board too.
The MSI B450 board looks good,but has pushed the front IO connectors to the rear(really?),apparently has conflicts with the stock cooler,and seems to not have proper voltage offset for PBO.
Sure the B450 can do overclocking but I don't really overclock anymore(outside enabling MCE or maybe PBO). In fact in general if you start going up the range AM4 boards are not really as cheap,which is utterly weird considering Intel still needs to use a traditional chipset,and AM4 chipsets for the most part are much more depreciated due to the SOC nature of Ryzen.
So now I am paying more for the motherboard than the CPU.
