I use a ton of USB ports

You only get 3 extra USB ports.

Here are 7 USB ports for $18.

I have more than 4 sata drives.

I have 3 SATA drives and use the 4th for my DVD ROM. If I ever needed more storage, I'd wipe my 1 TB HDD and replace it with a 4 TB HDD. I would not seek an additional SATA port. Especially for $100.

some people need more than the bare minimum.

Glad to hear that, because the $125 MSI PRO B660M-A DDR4 provides more than the bare minimum.

That combined with a better looking board

Subjective.

there’s a ton of stuff worth the $100 difference (for me and others)

I'm all ears.

Because right now, IMO(and many others), 3 extra USB ports, 2 extra SATA ports and 2 extra M.2 SSD slots does not justify $100 extra.

Especially when the $18 7 USB hub above saves me $82 and gives me 4 more USB ports. And the fact that I can make sure my first or second M.2 SSD I put into my PC is at least 1 or even 2 TB's and I can make sure my first or second SATA HDD is a good 4 TB of storage space each, leaving me with 2 free SATA ports. And I'll easily be able to do this because I saved $100 on the motherboard.

What are the remaining ton of stuff you speak of? I'm all ears.
