I would choose either an NL or SF in a 8x32 and a 10x32. I have an NL 8x32 and an SF 10x32. For my birding, I like having a 8x32 and a 10x32 for closer in birding and longer range birding. The NL and the SF are real close, so it comes down to personal preference. For optics, I think the NL is a tad better than the SF. The NL has a flatter field and sharper edges than the SF, so it depends if you like that or not. Some people don't and prefer the less flat view of the Zeiss. I think the SF is a tad better at CA control, especially on the edges, so it depends on how much CA bothers you.
I think the handling of the SF is a little better than the NL with its weight rearward balance, really comfortable armor and super smooth focuser. For me, it is fun to have both the SF and the NL because I appreciate the differences between the two, and it is fun to change off. They are both fantastic binoculars, and you can't go wrong with either. I think for most birders, the NL and SF in either a 8x32 or 10x32 are probably the best birding binoculars you can get if you bird mostly in the daytime and don't need a bigger aperture for low light. With either an SF or NL in 8x32 or 10x32 you are not going to suffer too much!
