I have several SR620 and HP5370 in my lab. My preference has always been the SR620; by size, features, front panel, calibration, programming. But both counters do the job so if you can find either one at a reasonable price go for it. The SR620 is still a current & supported product at SRS.
Over the years I've visited quite a few professional time & frequency labs and always see SR620's in use. Rarely, any HP5370. Not sure what that means.
Again, either one is fine for time nut use. One of these days I should do a detailed performance comparison among a large set of both counters.
