All other things being equal, the 8x will have a wider field of view, be
easier to hold steady and have marginally better performance in low light.
The 10x will allow you to resolve more detail at distance *if you can hold
it steady*.
It's very much a matter of personal preference. I would use 10x if I could
hold them steady, including occasionally one-handed. I cannot, and so I use
8.5x.
