What? They 100% do. Why would leading 8 strangers in a Milsim environment be any different across the two games. Wait I can think of one reason, one game has a massive population of console players which, sorry to be mean, are significantly less competent and harder to work with than PC players.
I can also tell you that project reality, squad 44 (post scriptum when I played it), hell let loose and Arma 3 (tho to a lesser extent) all play very similarly when squad leading in a public environment.
I went from squad to HLL, who have 6 man squads, and started leading there and realised “omg this is so much easier and less stressful”
I then took that experience and locked my squad in Squad at 6 players, and found the game way more fun.
It’s not just the leader, the players in the squad coerce better, talk more, learn each others names faster and work together better as a team overall.
It’s probably why competitive games like CSGO, VAL, league, and even almost all coop PVE games hover around the 5 player mark.
It’s just a better environment for teamwork with randoms
