I think you make a good point. I moved from hz1500 because of DoVi frame skips. Unbearable. I have a Sony a90j with no frame skips but the PQ is possibly not as good. I'm hoping a calibration in two weeks will remedy as I think pani is better ootb than sony. But I think sony pq can be improved. I loved my old vt65. Probably best tv I've had. Motion and pq on sky hd was amazing. I'm now on oled with sky q. I've gone backwards I think. Should have stuck with it but too late now. If it ain't broke.......
Well, my VT65 is boxed up and was never sold. I could sell on my HZ1500 and reinstate the VT65, but it's an old television with a smaller screen that won't last forever (although to be fair it was still going strong).
With SDR material I have to say the VT65 was probably, on balance, marginally better than my HZ1500. I should point out that my VT65 was calibrated while my HZ1500 currently isn't. Out of the box accuracy has probably improved over the years, but having watched a calibrated image for the best part of a decade I can tell the difference.
That was always my rationale for buying the A8 before ending up with the HZ1500 - if you're going to calibrate anyway, what difference does out of the box accuracy make? A calibrated Panasonic might make for prettier graphs than a calibrated Sony, but in terms of viewing the differences are negligible, especially when they're all using the same panel. Unfortunately a calibration would have done nothing for the A8's near black flashing issue. For what it's worth, although Sony's OLED motion is better than Panasonic's, it isn't problem free. I could still see occasional judder with 50Hz broadcast content.
I do feel similarly - if I could pop back in time and offer myself advice, I'd probably say "stick with what you've got; it works; you're happy and you're comfortable with it." Instead I chased something I thought would offer a noticeable upgrade that in reality doesn't, at notable expense.
