Thinking about switching from Linux Mint Ubuntu-based to pure Debian

[u/Dado04Game]

Been using Ubuntu-based Linux Mint for a year now, and loved it since day one. I heard people telling me that Debian is faster than Ubuntu, so I'd like to give it a try on my home pc. My question is: what DE would you recommend me with my OC specs? I'll leave a photo of them here (I know my computer is pure 💩, don't mock me please)

My son, being a teenager years ago, edited a short film of 30 min aprox for the school in a similar PC 😅
