Thats a very tricky question as recommendation wise it depends on what is being looked at. For general views of large diffuse nebulae and star clusters 70-100x. For globulars however, something more in the range 150x - 300x to get maximum resolution while galaxies anywhere between 100 - 500x depending on the situation. For those tiny planetries, 600x to bring out the details if the seeing supports it.
Overall, the 7mm Nagler spends most time in my focuser which gives 292x in the 18 inch or 238x in the 12 inch so that would be my personal favorite.
I feel pretty miffed if the seeing doesn't allow at least 200x but fortunately, thats not too common at my main dark site.
