I am upgrading my 2015 iMac to a 2019, on my current iMac I have a OWC thunderbolt 2 dock which I use as a USB hub. I get really good transfer speeds from this setup. I would like to duplicate this in my new iMac. Would the Thunderbolt 3 to 2 adapter work well or will I be better served selling the TB2 dock and getting a TB3 dock. If so, any recommendations on a TB3 dock?
