I have a Zeiss 5 power...good quality, but I don't like it much. Have tried some other monoculars, but I guandamntee you those pirates in the movies couldn't see crap through a hand held telescope on a moving ship! If you can really see anything really clear when you're not using a good rest, you have better eyes than I do!
Also have 8 x 20 Leitz binos-perfect size, but they aren't bright enough at last light. Tried 10 x 25 Zeiss with the same complaint. My best small glasses are 7 x 35 Swift Audubons and Vortex 6 x 32s. I go bigger when I can stand the weight, but a really good 6 or 7 power compact is my go-to hunting bino. Reasonably small, light weight, great eye relief, great light gatherers, with especially clear, crisp views. I'll suffer whatever to carry a glass like this.
