I agree, it's not a cheap set and I don't expect most people to go to that level. It's just now that I have had it, it's hard to take steps backwards in some areas. I have my eye on the Sony Z9D, but even that's beyond what I think I'm willing to spend right now as it's even pricier than what my current set cost at the time. I'll elaborate more in a bit though.
I agree it's a personal preference, but let me elaborate on my stance on the whole thing. IMO, my first recommendation is to not buy a TV now; it's premature. The HDR standards just got defined this year. Only a few sets actually conform to those guidelines and things are in flux. Most don't stack up. I firmly believe next year is the first viable year that someone might be able to select from a wide range of decent HDR capable sets that are up to the quality level that they should be. The dust is still settling and I think it's premature to buy now. If money is your concern, don't buy now.
That said, if you must buy because your set just died, then I'd first recommend the Sony Z9D if money is no object, then the LG OLEDs if you don't want to spend quite that much and if you're more on a budget look at some of the higher end Samsungs and finally on the lower end the Samsung KS8000, maybe the Vizio P series, and then the only one under a thousand if you wanted to go cheap would be the Sony 800 model. I couldn't IMO in good conscious recommend the Samsung 6300 to anyone who was looking for a TV to buy today because of how it handles HDR. I believe HDR is a big thing and getting something that's so far off from what is going to be offered to me is just throwing your money away when there are better options out there now and there will be a lot of better options next year.
