Intel cost is part brand name cost, part limited production figures cost. They are also one of the few makers who actually include VRM temperature monitoring, so you can be sure their cooling schemes are adequate - it honestly doesn't take much more than simple heatsinks to cool a modern motherboard.
And really, how many of the "extras" are you likely to need. Most included junk is just that, and a cheap way to boost perceived value
, which is what consumers and marketing alike use to justify cost.
Have you considered finding a model that could work reliably with SpeedFan? It's a bit more work than Fan Xpert 2, but results achieved can be very good indeed.
AND to provide an answer to your question: I would go for value rather than bells and whistles. After my Asus Maximus II Formula blew up and took the processor with it, I've been rather disillusioned with the premium category. Unless the model has some serious issues reported widely, a long warranty is your best bet, not a long price tag.
