You should have led with this and saved yourself the time spent reading irrelevant suggestions from amateurs or professionals making incorrect assumptions about your specific goal. Consider adding this information prominently in your original post.
Regarding your actual question, I’m afraid you will likely need to try a few jigs yourself and may end up using different ones in different circumstances. Caveat – I’m not a professional, but I have installed a few doors, some relatively recently, and I was also researching potential jigs.
All commercial jigs (at least those I’ve looked into) work well on the door side, but far fewer work acceptably on the frame side. Almost none (that I’ve seen) work on an existing frame with door stops and/or architraves installed, and in some cases, removing the existing stop/architrave to fit the jig is not desirable.
That said, given your experience, I’m curious to see which jig you’ll find acceptable. When you find ‘the one,’ please post it on this thread.
