My cabin on the cruise ship we're on has a pair of Meopta 8x42 Optika HD binoculars and they're very impressive. Much better than the Bausch & Lomb pair I bought about 20 years ago. Only issue is the weight, even with a magnesium frame they're pretty heavy.
What other binoculars have you been happy with?
If you want the best optics currently on the market, then you want the Fujinon FMTR-SX 7x50 marine binoculars. They are not cheap ($700 USD at B&H Photo today), not small, and not light (over 3 lbs), but they are the finest you can get. I have the long-discontinued Pentax PIF 7x50, which rival the Fujinons, but you can't get them, anymore, and they are even heavier, I think. If you want similar quality, but a much smaller size, the FMTR-SX used to also be made in a 6x30, but good luck finding any on the secondary market, they are as rare as hen's teeth, and jealously guarded.
Generally speaking, the best binoculars on the market are going to be the ones marketed specifically for marine use, and those will usually be 7x50, because the widest a human pupil can open is about 7 mm, and 50/7 = about 7.1 mm, so a 7x50 actually captures more light than anyone's eyes can see. When you look through a pair of 7x50s, the image will actually be brighter than that which you naked eye can see, so when you use them in dim light, it almost looks like looking through night vision goggles. Marine binoculars are also generally waterproof (for obvious reasons) and heavily armored (because boats have a tendency to move around a bit). This is also why they are so commonly used in the military.
Porro prism binoculars are much easier to make to a higher optical standard than roof prism types, but roof prisms are generally more compact. That's why roof prisms are popular, and why the best ones cost thousands of dollars, yet still can't quite match the quality of the best porro prism types.
6x30s are a good size for compactness and lightweight, and 6x is a good power for handholding. 7x50 marine binos are also generally great for binocular astronomy.
Other than that, most of the binos by the big names (Nikon, Fujinon, Pentax, Zeiss, Swarovski, Leica, Steiner) are going to be good.
