Having had the Zeiss 7x50 B/GA and later the Zeiss Victory FL 7x42 for many years, here's my take.
The FL 7x42 was showing me views I enjoyed much more than the 7x50 B/GA. And I found it easier to focus (because of it's center focus) with more eye relief and better adjustable eye cups. At almost half the weight, it was also much more convenient to carry and hold. 3D effect goes to the 7x50 porro, but the 7x42 Victory FL was still quite OK in this respect. Compared to 8x42's, big low surface brightness objects are easier to find and observe.
7x is a wonderful lowish magnification, with generally smallish apparent and -true fields. There are very few notable exceptions, approaching 60 degrees AFOV. All in the 42mm roof variety from premium makers for a premium price: Zeiss, Nikon and Leica come to mind.
These exceptions open up the skies in a grand way. Offering, bright, wide, stable involving views in a hand held instrument. But in the end I generally prefer 8x wide AFOV binoculars to differentiate deep sky objects from stars and see more detail.
If I wanted 7x binoculars gain, I would choose one of the scarce 7x42 high end roofs. Lightweight, wide and involving views. Edge of field is not very sharp in the few models available up to this date.
Once I got my Nikon 8x30 EII, my Zeiss FL 7x42 no longer saw any significant use. Perhaps because I also have an FL 10x56 as well, from the moment I got it my preferred hand held instrument once the night falls.
By itself though and as an only instrument, a top quality 7x42 wide field roof is a wonderful instrument.
