That's an old article and compares second gen Ryzen to the 9900k. There are no third gen Ryzen chips in those charts.
You mentioned Premiere Pro and After Effects, so it seems multi core performance is a consideration.
The 9900k is an 8-core, 16-thread 14nm processor vs. the 3900X at 12-cores, 24-threads and newer/smaller 7nm process for about the same price. With Ryzen 3900X you get higher core count, better power efficiency, faster base memory spec, and the only platform with PCIe 4.0.
I also like that AMD does not make us upgrade motherboards nearly as often as Intel. You can still run almost any Ryzen chip on some very old AM4 motherboards, whereas Intel forces us to buy new motherboards with almost every chip iteration.
Anyway if you are not in a hurry and want the very best, you could wait for the 3950X to come out in November. This will be a 16-core, 32-thread Ryzen processor for $750 that beats Intel's $2,000 i9-9980XE. At that point, Intel will have nothing to compete with Ryzen. It will be a while before Intel can even get 10nm chips in production, while AMD is already on 7nm.
Flip through some of the benchmarks on this Tom's Hardware article and you can see why they picked Ryzen 3900X as the winner:

In a few tests that favor Intel or higher base clock, the 9900K wins by a small margin. In almost everything else, the 3900X wins by a large margin.
Currently Ryzen is the leading platform, evidenced by the die size and PCIe 4.0 coming out on a Ryzen platform, not an Intel platform as it normally has in the past when Intel was in the lead.
They're both good chips and I'm sure you'll be happy either way, just wanted to offer some perspective for consideration.
