Late to the party. Both excellent calibers.

If you reload. 7-08
If you don’t reload, 6.5 CM. 130s. Shoot flatter and hit hard in normal hunting ranges rather than 140s. IMHO 140s you need PRC.

If you plan on bigger than deer 7-08
Edit.
I reload and bought my 6.5, before Covid.
Deciding factor was S&B box of ammo was 10.99 for fmj and 11.99 for PSP.
7-08 was double that

All of them do something better than the 30-06, but none of them do everything as well.
