You can probably do a standard velocity 120gr load on the 6.5 whereas you'd want a reduced load with the heavier 7mm bullets. Around here a full-house 120gr .260 and minimum load 130gr 7mm08 get the same reception.
The only way I'd go 7mm08 is if somehow stuck on using over 129gr as the minimum weight in the 6.5. Might as well use 7mm08 if going much over 120gr.
