Out of curiosity, why do most here recommend AMD builds over Nvidia/Intel?

I've spent the better part of a year researching and attempting the perfect performance/budget build. Forums, social media, YT, etc. Everything so far, has pointed me to the Core I5 13600k for CPU (solid for gaming and overall performance while being budget friendly), and 40 series cards for overall performance because of DLSS, and RT (if you're an RPG, scenery nerd like myself). Genuinely curious as someone who is new to this sub.
