no its not better. than both GTA and red dead.
Everyone is entitled to their own opinion. I personally just don't rock with GTA or RDR2 because Rockstar makes the most technically impressive worlds and basically does jack shyt with it. Los Santos in GTA 5 was so gorgeous and detailed that I remember driving by many of the locations in the game in real life here in Cali. As far as gameplay and mission structure was concerned though it fell off a cliff after the first heist.
So many of the missions were Go to Y and drive/fly/boat to X, kill the guys, steal the thing, drive/fly/boat back to Y. This game play doesn't take advantage or even interact with the beautiful landscapes that Rockstar created. When you get in one of these missions you go from one of the most technically amazing open worlds to a linear shooting game that requires auto-aim to make up for its deficiencies.
It's basically the Fast and Furious of games, it's awesome if you don't expect too much from it. I personally think GTA IV was a much better game because at least it had a compelling narrative.
