Coming back to original topic, in Solus there are (usually) Friday syncs, where the stable gets synced with unstable. So on stable you get an exact copy of what unstable users were testing for up to a week (and in terms of bigger updates like current huge stack upgrades - 2 weeks), so it is easy to control everything, test thoughtfully, and pinpoint the problem.
With Manjaro they delay everything by 2 weeks, so it is harder to test everything together, because both stable and unstable are constantly moving and are out of sync. I doesn't necessarily have to be problematic, but Solus makes it easier for the team to keep things stable.
