I've worked up a dozen or so loads with H4350 over the years. Then a few years ago I couldn't find a pound of H4350 (or any 4350 for that matter) within 200 miles. So, I made do with Win 760 (same as H414) and found it was very good-- just about equivalent in all respects to my H4350 loads. I now think you could be happy with either powder in 30-06.
If you are worried about temperature sensitivity-- maybe go with H4350 since folks say it's temperature insensitive. I hunted coastal California for many years with what turned out to be temperature sensitive powders and never knew the difference. It just wasn't an issue.
If you want to use a powder measure, the H414 (Win 760) wins hands down.
Good shooting!
