Refurbished 500 gb is 410 $, OLED 500 GB is 627 $ (in my currency ofc).

I’m really unsure if it will be worth it, especially that I have limited budget, what do you think? Is the upgrade going to be much better?
I plan to play mostly indie games on my deck and titles that I wanted to try for a long time like Yakuza, Dark Souls or Elden Ring
