RBK353 better than Velop?

I recently purchased an Orbi set up (RBK353-100) to replace a Linksys Velop systemthat says it is Tri Band. Reason for this was I did not think the Velop system was handling device switching etc very well and disconnecting quite a lot. Orbi has been fine so far however the question is this:

The Orbi says it's WIFI 6, and having read up on this most say WIFI 6 is Tri Band. But the product I have got says its dual band. So have I replaced a product with an inferior one?
