Very close betThe 7x57 has done it all for about 100 years, but it is based on an unusual length case. Its overall length is just slightly greater than what can be accommodated by most short action rifles, so it is usually found in standard length actions, where it's performance is outclassed by longer cartridges like the .270 and .280. Mauser once built a special intermediate length action for the 7x57, but none of the major rifle makers do so today. Which eventually opened the door for its ballistic twin, the 7mm-08 Remington.
The 7mm-08 is a true short action caliber, based on the .308 Winchester case. It is the most practical and has become the best selling of all high intensity 7mm's. It makes no pretense of competing with the .270 Winchester, and so has avoided the comparisons that doomed the .280 and .284. Shooters have recognized that it is one of the best balanced short action cartridges ever designed, and it has become a legitimate all-around cartridge.
I have a 7mm 08 I shoot a Sierra 150 grain match king with 48 grains of V160. 2820 fps. It works for me.
