Any Specific Order?

You're Tom's Hardware that everyone comes to for mainly for gaming, you could of at least had a basic metric you used such as a 3dBenchmark that you listed them in.

Such as, for that link you said whatever benchmark they used the 7400 is 3% faster for the gaming, even though you have the 3770 higher up on your list

If I wanted to stare at a list of CPU's that were not in any kind of valuable order, I'd just keep staring at Newegg.com all day long reading and keeping up with the current market.

I thought you guys at least had some kind of "hierarchy" being you claim they are listed in a "hierarchy" not just some random thrown together list you seem to be telling me it is.

Thank you for the new website I can use from now on that actually has real-world relevance to suggesting to people whether or not an upgrade would profit them and allowing me to cut out the middle man website that doesn't help me in real-world.
 
You can't really have a 'basic metric'. Let's say we all agree we all game. Great. Someone plays a bunch of 2d games(Undertale, etc), someone else plays classic 3d games(Deus Ex, Half Life 2, etc), someone else plays newer games like GTA V, someone else plays bleeding edge games like Assassin's Creed Origins.

How do you devise one metric that serves them all equally, when things like settings/ram/videocard all can affect performance AND affect performance differently for each person?

The best way to get help to choose a CPU is simply to specify your needs. "I want to play X game at 1080p high settings" and then people can suggest the CPUs that would allow that.
 
As I said, too many variables to consider, all you can do is to compare 2 IDENTICAL systems, running exactly same game for instance at same settings.
Other things to consider is also affinity of some programs/games to single and multi core processes.
An i3 at high single core frequency may be better than an i7 at lower frequency in single core applications but i7 would be way better in multi core applications.
