There is a huge difference in killing power between the two. Just a few numbers to consider.I kind of had the thought recently... what can you do with the 7mm-08 that you can't do with the .243 win??
Of course the 7mm can be loaded heavier for bigger game, but honestly, personally, if I can't get it done well with the 243, I think I'd move to a bigger cartridge like 270, 280, 30-06...
nothing against the 7mm-08 though, or 308,

7mm-08 with 139 grain sst per hornady site (energy at);
200 yards - 2040lbs
300 yards - 1768lbs
400 yards - 1524lbs
.243 with 95 grain sst per hornady site (energy at);
200 yards - 1478lbs
300 yards - 1217lbs
400 yards - 992lbs
The simple answer is you can deliver much more energy on target with very similar trajectory allowing you to cleanly take larger game at longer distances. The .243 is just under the recommended foot pounds of energy for an elk at 200 yards while the 7mm-08 is still over the recommended 1500 lbs of energy at 400 yards.
The main advantage to the 7mm-08 vs going to one of the cartridges you mention is felt recoil. From 0-400 yards it is delivering plenty of knock down but easier on the shooters shoulder. Not for everyone but a great choice for many...
