Personally I assume if a project is at least somewhat popular it works most of the time and frequent/serious bugs are reported and researchable. For that to work I also report or second bugs I encounter. That doesn't mean there aren't any bugs in even the most popular OSS, especially in edge cases and rare scenarios.

With closed source though I often don't know the popularty and how many/what kind of bugs have been reported, but just the reputation of the vendor.

I prefer a popular software from a highly reputable vendor over a somewhat popular OSS. But I also prefer the most popular and battletested OSS, like postgresql and linux, over any closed system, e.g. SQL Server and Windows.
