Its hard to break off and say that any Football Manager game isnt the most indepth and close to real life experience you will get, but on a console, thats exaclt what it isnt.
Using your Xbox control pad, this game doesnt feel the same as it might if you were to play it on the PC. The PC offers you a lot more power at your finger tips because it is Mouse and Keyboard. Using a Control Pad with 8 Buttons, a D Pad and two annalogue sticks is hard. Typing in the search bar is hard, even if thats Microsofts fault, although if you choose, you could plug in your messenger kit or a USB keyboard and type that way, but then its basically a PC anyways, and given the Minimum Spec on the PC version is pretty low because of the basic gameplay and graphics, its probably advisable to go for the PC version.
If you want to manage on your 6 Processor Xbox 360, try LMA Manager 2007 for this year.
