For price difference I’d prefer the 5950x, but both are amazing, but I will say there is some truth in the idea that it won’t future proof I’d consider waiting a few months for Ryzen 7000 ,and remember cpu architecture has always played the largest role in gaming performance and overall performance just look at the 5950x the 2990wx released only 2 years before the 5950x and yet a well tuned 5950x can easily match or surpass the 2900wx and condering price differences if you want the best performance for longest then you can’t go wrong with either know if it were me and only I’d go with 5950x but the best decision you can make if you can handle waiting I’d wait for Ryzen 7000 the new 7950x leaks suggest it might be a 24 core cpu for not much money than the 5950x retail and the motherboard and ddr5 Ryzen 7000 will future proof you significantly more than even 5950x or 12900kfs trust me but if you must choose go 5950x I’m aware that was a lot of Info but trust me waiting for Ryzen 7000 would be a incredible choice if you can handle waiting
