Sold the HK and Sony lines back in the day. HK gear all sounded great but was very spotty on quality and their Sendust heads fractured when cleaned with Blue Shower (a common cleaner back then). Sony TCK777 was a bullet-proof tank, but a bit flat even when biased correctly for the tape. Never cared for Denon; overpriced under-performers with fragile switchgear and cosmetics. Onkyo and Yamaha had excellent build quality but like Sony, a bit more appliance-like in sound. Onkyo was price-competitive with Sony back then and Yamaha wasn't.
Caveat emptor on all of these because parts are next to nonexistent. I'd have to put Sony first, Onkyo then Yamaha. If you really want to go into this world and are serious about the sound, don't neglect looking into Nakamichi 582, 700ii or Tandberg TCD440a. Pricey, tweaky, expensive to operate and maintain, but oh-so worth it. Tandbergs are available refurbished to an as-new condition from Soundsmith. The Naks have all the same problems as the other Japanese stuff, but they also have a dedicated and loving fan base the others never enjoyed so some support remains available.
Good luck & happy listening!
