There’s no real reason to use it over Arch/EndeavourOS
Their holding back of updates for 2 weeks is stupid and can cause breakage/dependency issues when you also have stuff installed via AUR (which doesn’t get held back for 2 weeks)
They hold back packages for 2 weeks, citing stability and that they can check for issues then patch before they push, but then they just… don’t do that. Known issues still get pushed.
Manjaro repos have had issues with malware in the past
Manjaro has on multiple occasions had their SSL certificates expire, with their advertised “fix” being to roll your system time back. This is a job that can be automated, or at the very least should have a reminder for someone in Manjaro to sort out. The fact it happened once is an embarrassment, but the fact it’s happened more times is absolutely inexcusable.
