There are two competing forces, weight and power.
For the everyday carry (ok, not edc, but usual binoc use), I've had Vanguard Endevour something or other in 8x42. I have a generation or two old, but they are great.I'm sure Leica's would be nicer, but if I drop them or bang them on the rocks, I don't feel too bad. New ones are $325 for ED and $275 for the ones I have.
For Power, Cannon Image Stabilizing are fantastic They are heavy, but for 15x50 or 18x50, the battery powered image stabilizer is priceless. (Ok, its over a grand)
If you are going to use them, a harness helps. It keeps them out of the way when you aren't using them, but strapped to your body.
Just find a local birding club that has group outings. The optics you will see will be astounding.
