UT has been garbage for some time. I reckon the data it uses to send your info back to them and to load ads, bogs down the network, especially on slower networks. The last time I used it, there were also graphical artifacts all over. Qbit on the other hand, is much cleaner and simpler to use, and it doesnt add any unwanted network traffic, which is why it’s probably faster
Depends on what you want. For games, find a trustworthy repacker (fitgirl and dodi are good in my experience) and only download from them. For software, again, it depends. For adobe products, M0nkrus is pretty good, but I’m unsure about other software. Movies and music are typically quite safe as long as you practice due diligence (basically dont open a file called song.mp3.exe).
In other news, the floor is made out of surface
