There are a lot of reasons why the 7-08 is popular.
First and foremost, it is inherently accurate.
In addition, the 7mm class of bullets is probably second in popularity only to the .30 calibers, so different bullet weights and styles are easy to come by. Also, due to modern powders, one can achieve long caliber balistics from a short action round, making it extremely versitile. This caliber can be hand loaded for everything from varmits to moose. The list goes on and on.
Sounds like you made a fine choice to me.
