For me the benefit of AUR isn’t necessarily the ease of download. It’s the fact that it’s community based and anyone can build a package for any software. I always git clone and then makepkg. I hate using yay because I want to read the PKGBLD myself and check the hash. I’ve found some obscure software via AUR that I wouldn’t be able to easily download on other distros. Further more the AUR website allows comments from the community which encourages bug fixes and/or a dialogue with specific package issues.
