Snapdragon mas optimized sa halos lahat ng andriod application especially when it comes sa games.
For custom rom both mediatek and snapdragon available yan.

Android games: both
Emulators: Snapdragon

MediaTek

Both, but Snapdragon is in the lead
4.issue
MediaTek: Generally hard to root, depende na rin sa manufacturer (closed source)
Snapdragon: from what I've heard, hard to unbrick especially with wiped out system firmware partitions (wala ako experience with SD SoCs)
Based on my experience, agree talaga ako na Snapdragon ang mas lamang. Although, gamit ko ngayon is Mediatek which is Helio G90T. Actually, nakakasabay tong si G90T sa iba kasi yun na nga problema, grabe sa heating.
Also, if you're into emulators (Aether SX2), the best mag emulate sa SD because of Vulkan.
Sa price, mas budget talaga si Mediatek, medyo pricey din kasi SD pero sulit lalo na kapag SD 800 pataas. If Mediatek, go for Dimensity processors, sumasabay na talaga. But for now, SD still wins.
solid parin snapdragon in terms of compatibility lalo na sa apps
g90t palang recent na nagagamit kong mediatek okay naman para sa price.
pero cant say the same for dimensity phones daming good feedback ng dimensity 8100 pero mas okay talaga kung ikaw mkakasubok
