GTA 5 is widely considered the best GTA game because of its three-protagonist structure, which lets players switch between Michael, Franklin, and Trevor for very different perspectives on the same story. Los Santos is one of the most detailed and lively open worlds ever built, packed with heists, side content, and dark satire of California culture. And GTA Online has kept the game alive and evolving for over a decade, giving it a lifespan no other entry in the series comes close to. Of course, plenty of fans still make a strong case for San Andreas or Vice City instead.
