Yes, 100% prefer the Treyarch games. Even their worse games, in my opinion, were better than mw19. This is due to the flow of the game.
To be fair, I understand that the devs eventually figured it out too, and started releasing better flowing, smaller maps into 2019. But, they had to grab me at the beginning, and at the beginning it was huge maps, with 1000 windows and line of sights, ghosts was always active, people were encourage to camp. We even saw posts by devs saying how this game was made for newer players.
Anyhow, I get if after with shipment and smaller maps it got better, but definitely not at launch. I remember even visibility being a problem.
I also prefer scorestreaks over kill streaks.
Anyhow, funny enough, youtubers have already said that when they got flown out, they were told 6v6 maps would be more of the classic route this time around, so I think they heard the feedback.
I can also commend for 2019 looking beautiful, and sounding amazing, and glad it brought cross play, cross progression, and got rid of season pass. I can appreciate all that, but the flow of the game wasn't it.
