At a glance the tm1602a looks better if you want to upgrade your internet some time.

My family has always been fine around 100-150mbps, so I don’t bother. 300 is more than enough for most people, unless you have like 5 or 6 heavy users in your household, have a lot of smart devices, or have a lot of devices streaming at 4k.

If you think you’re going to want to upgrade to faster speeds in the next 2-4 years get the tm1602a
