So running a 6502 on an Artix-7 or W65C02S, is this more or less the most you can get out of it. That is does it max out the available logical units on the respective chips? Also do you get a 1:1 speed, when it comes to frequency etc?

"Artix 7" is a family of devices. The "Arty A7" he's using comes in 2 choices...the A7-35T for $119, or the A7-100T for $249. The picture seems to show the A7-35T.

The MEGA65 runs on the A200T variant of the Artix-7, and claims to be 50x faster than a Commodore64. Also, you can find a few different 32-bit soft cores booting linux on Artix-7 FPGAs.

(Though, as mentioned, the article is not about emulating a 6502 on an FPGA)

No, the Artix-7 is a bottomless pit of LUTs, DSPs, and BRAMs. You could probably fit a ton of 6502's in it.
This isn't simulating a 6502, this is how to connect and test a "real" one to your FPGA
I would guess that even on the most inexpensive FPGA (iCE40 for example) you could run a 6502 at at least 20 MHz, and fit some display logic on there as well.
