The savage axis is different in many ways to the big brother line ups.

The stock is more flimsy. Particularly around the fore end and the grip, it also feels slippery.
The action bolts are in different positions (closer together) than the other guns (which seem to be a standard space apart) so you can't interchange stocks.
The recoil lug is separate from the action on the axis, my 116 and 11 has them part bolted together as part of the action assembly.
The safety has a lot more plastic on the action in that area vs my 116 and 11 which is alot more metal.
The action is closed more on the axis with a smaller slit to reach your hand in to load rounds or clean etc, my 11 is way more open on top.
The bolt is plain polished vs my 116 which is a bit more decorative and jeweled.

If you have the extra money go with the 10 or 11.
