I disagree. Like David Lowry stated, Elmax is not necessarily better than S30V. Especially in ZT's case, I would go for S30V. I don't know if ZT fixed the issue by now, but there were a lot of reports of the messed up heat treat or burned edges of ZT's Elmax on the 0560. Now if you would be ordering a custom from FerrumForge or something, I'd say go with Elmax, but with ZT I'm not so sure (yet). Their S30V is proven to be excellent at least. Further, it all depends on what you want. The recurve of the 0350 could be just as "utilitarian" for you, depending on your liking. Also, both knives have a detent-ball and -hole and can be de-assisted (which I'd prefer). Further, the 0350 has a bigger/beefier handle and could thereby be fitting you better/more comfortable than the smaller 0566.
To be honest, I'm doubting the same question as you. I like the 0350 more, except for it's ridiculous weight. I've inquired several knife pimpers already with the question if they could mill-out/skeletonize the liners of an 0350 but I didn't get any positive answer so far yet. Also since I'm used to edc a Millie I'm scared the blade will be just a little too short for my liking...
