Depends on your use case.
I only buy phones that have a non soldered connection and the case can be (with reasonable effort) opened.
Yes, phones with a bad repairability score are shit. But a phone without a shell that can be easily opened doesnt necessarily mean that it has a bad repairability score.
As I said in other comments: it's a matter of preference. For me the pros of a closed phone outweigh the cons. For you it obviously is different.
