If you own PSX/PS2/GCN disks, is it better to play OG or emulate?

After Yoshitaka Murayama died, I decided to finally pickup Suikoden V and complete the series.

I also figure Im gonna do a complete playthrough.

I still have my PS2 with component cables. Would it be worth it playing legit, or are the small quality of life elements from emulation like savestates and speed changes reason to do it that way?

This also applies to any other games Im thinking of replaying, I mean, if I DO emulate I can play them on Steam Deck, which would be sweet.
