Which game is harder WOW classic or Wow P2P or OSRS or RS3?

(I have not played wow so forgive me on my lack of lingo)?

Wow =World of Warcraft

Rs = Runescape

Osrs = old school Runescape

P2P = Pay to play

F2P = free to play

My Experience is that I had played OSRS and a bit of the RS3. But I have not played these mmorpg in like in a decade.

(Please dont say it depends, I am asking regards as wholistic society perspective and then personal perspective.) And in Order if you can. from easiest to hardest for example.

OSRS
RS3
WOW classic
WOW

I honestly think rs3 is harder in terms of the developers intent. (The fact you can buy exp exp lamps in rs3 is just terrible. But ignoring stupid stuff like that. There is so much fluff with rs3 it ultimatly makes a game that is 15 years old a more compelling version of itself.

RS3 is a very nice game but stop it with fluff omg.

Ultimate Hardcore Ironman of OSRS, would probably take the cake in terms of hardness. Super grindy

Honestly the way to go about MMORPGs I would do OSRS Ultimate Iron man that grand exchange really does streamline the game makes it unnatural.

But holy crap that game is time drain. OSRS Hardcore UIM I would imagine would be the most difficult in the idea that it is mindnumbingly masochistic on the amount of time spent on it.
