What's the tangible difference to the user of Docsys 3.0 vs Docsys 3.1

*What's the tangible difference to the user of Docsys 3.0 vs Docsys 3.1?*

The only disadvantage, that I can think of, to owning your own modem is that
it's most likely locked to Docsys 3.whatever (at the time you bought it).

The last modem I bought was Docsys 3.0 years ago (still in use by the kids).

Nowadays Costco sells these two which are Docsys 3.1 modems (not Docsys 3.0)

What's the tangible difference between Docsys 3.0 & 3.1 to the avg user?

It's spelled DOCSIS:

The main difference is the maximum speed. You will need a DOCSIS 3.1
modem to obtain over 1 Gigabit/sec data rate. Some DOCSIS 3.1 modems
have two ethernet ports that can deliver 1 Gigabit/sec each. Others
have a single 2.5 Gigabit/sec ethernet port. Still others have one of
each. This might help if you're comparing features:

Note that a DOCSIS 3.1 modem is downward compatible to DOCSIS 3.0
speeds. If you want to future proof your modem purchase, you can buy
a DOCSIS 3.1 modem and use it at DOCSIS 3.0 speeds until you decide
you need speeds over 1 Gigabit/sec.
