Now, I may be biased as a long time fan, but I still play MGS1 every few years and I still love it. The first two (or four, depending if you want to count the NES games) Metal Gear games, those are far more outdated and are more a curiosity and are not really required to understand the story, especially with the interview / interrogation of Snake extras on the MGS1 discs.
And the later games are even less outdated than MGS1. I would recommend starting with MGS1 on the PS1 rather than it’s remake since while Twin Snakes was made under Kojima’s supervision, the more Hollywood action movie style of it and especially it’s cutscenes don’t IMO really fit MGS1. It’s a good game in it’s own right for sure, but as an adaptation/remake of MGS1 it’s kinda hit or miss at times.
