I use binoculars almost every day of the year. Have tried so many I cannot count them. My conclusions are that I now use only 10x. I have larger and smaller ones but all 10x. Don't need more and no use for less. Jmo
Swarovski 8x50 slc... heavy but I can see well into twilight and with a cloudless night you can still detect animals moving around pretty well. Opens up the night sky in light polluted areas better than anything I have tried yet.
