Similar (perhaps slightly lower given verification efforts) concerns about integrity/supply chain (who is maintaining this package really? Is it a clean build from the correct source?), but distro independent and often works good enough with some exceptions. Sandboxing is limited but better than nothing.
Once I somewhat understood the process and where everything is on GitHub (fairly transparent with CI stuff) I felt a bit more comfortable with things, but a lot of the store interfaces leave a lot of questions unanswered about the source (location) of the software.
If something is out of date I can usually make a GitHub issue and it'll get sorted soon enough.
Not the worst experience I've had.
