Opinions and advice regarding Metal Gear

What's your opinion on Metal Gear Solid V: The Phantom Pain? I've been playing for a few weeks thanks to the rona and really getting into it. I played Metal Gear games as a kid but I hardly remember any of it, how should I go about playing the others? Chronological or release order? Also, is MGS1 important to the series, as it's the only one I can't readily play. Every other main series game is accessible via PS Now. I can't run the PC patched version because I only have a laptop with 8GB RAM and integrated graphics. Also, what's the best game in the series?

metal gear is for me one of the best video game series of all time, almost all of the game is very good, specially the 3 and 5
