I own and have played the Gameboy remakes a few times. I would say going 1-2-3 shows the progression of game mechanic development really well - each feels like a refinement of the previous with some fresh new ideas added in. Additionally, though it's a fairly loose tie , the story across the 3 of them is related. That being said, though, I believe 2 is pretty widely considered to be the worst game in the entire franchise, so... Your mileage may vary. It is admittedly the one I've played least, and I probably haven't picked it up in the better part of 2 decades, so it's a bit vague for me anymore.
