Dave, If I was not traveling today I would have made 5370/SR620/CNT90/DTS2070 comparison measurements. I have done some before, but I am not sure that I still have the traces.
There are two measurements to be made, one on sine trigger and one on square trigger. I use a modified TADD-2 to square up.

If I am not mistaken, one I looked at had options to allow its use to 15:GHz, which might be nice for me as I do a lot of microwave stuff. But I suspect such options are expensive and I would be better buying a microwave frequency counter and a lower frequently TI counter. I have an old HP microwave counter, but * It doesn't have the GPIB option or any other options for that matter. * It has a fault * It is nowhere near as sensitive as a modern unit So I can't really be bothered to try to fix it.
