From what I've read, the 6.5-300 is only marginally better than the 26 Nosler, some saying not enough difference to talk about.
I have the 26 Nos, not the Wby, so I can't report on a side by side comparison.
I ran a thread on this before buying. I picked the 6.5-300 only because of the rifles in which I could find them chambered and their relative costs and features.
