Be careful with x570 if you require a lot of sata ports. Some come with as little as 4 even on top models.
In your case the TUF has 8 and the Tomahawk has 6.. be aware of the sata port counts if you require a lot of storage to be added.
I personally would go with the TUF out of the two you have there.
Or this one if you want 8 sata and spend about £220 but has no wifi:-

Or if you want to spend just under £250 (NO WIFI and only 6 SATA) then the
Asus PRIME X570-PRO AM4 DDR4 ATX Motherboard can be had for £245 , OCUK are out of stock but other places have them for that with free shipping.
Out of all the TUF would be my choice as it has everything 8 SATA WIFI etc. If I was on a tight budget, if not get the Asrock x570 Tachi they can be had for £309 with free shipping .. so shop around. That's the board I got and it's great value for £309, want something to last for next gen cpus this is the one and Asrock have always been great for issues even out of warranty they have fixed or replaced things for me at our company, thankfully for my home builds never had a issue and they seem to last forever and not fail randomly when you go into the higher end Asrock boards. ASUS are great too but their support can be a pain in the rear when things go wrong or you need to RMA.
One of my favourite boards was a Asrock Fatal1ty Z68 Professional Gen3 and was always rock soild and new person that purchased it still using it to this day over almost 10 years now.
