I have always felt the combo of 10x magnification and x40/42 form factor worked really well. Choosing a binocular based on handling and weight might make the he-men humping x50 plus class binoculars sneer at "weak arms", but as a tool for finding and (just as important in my birding) following birds, I find a quality 10x42 or indeed x40 really hard to beat.
I used (and still use, especially when travelling) a 10x40 Dialyt for quite a while but since buying a Nikon 10x42 SE during the Covid year that has been the binocular I've used most by some considerable margin. Practice and familiarity have mostly resolved its quirks (blackouts, handling) and the qualities that impressed me then (light weight, image quality) still do today. I use other binoculars for their charm and nostalgia, but am aware of their limitations. This (and my 8x42 FL) is better than my eyes. It's what I use when I want to give myself the best possible chance.
