I only experienced issues with OpenSCADs STLs if I used `difference()` with overlapping surfaces (aka when it flickers in the preview). Even then the slicer's repair feature fixed it.
For me the main limitation in OpenSCAD is the UI: distance labels along the XYZ axes are unreadable when they overlap with a surface, transparency only works with one object at a time. Also I'd love highlighted edges in the preview & split view, it would make alignment of parts so much easier.
Still I'm so much more productive in it than e.g. FreeCAD because I have most of what I need memorized and the rest can be looked up on the one-page cheatsheet.
