How safe in general is it to install from those OBS repositories (compared to official repositories)? For example if I install gimp from say home:Sauerland - can that be potential malware or otherwise damaging to my openSUSE system?
In general it is probably that most OBS repositories are “safe” … but the ultimate decision is down to you of course, I would assume if anything untoward was found it would be fairly quickly reported.

In that particular instance I would regard that as “safer”, if that’s the term to use. “Sauerland” is a regular and respected contributor to these forums.
