I don't know your heli but if it is tilting far more than your friend's maybe your swashplate needs to be leveled. Just a thought.
Read his messages again. He says that his helicopter is stationary. If the swashplate was not level, then the heli would not be stationary.

Now since you made me read the messages one more time, I have another probable cause of the difference in the "lean angle" between two similar helicopters in stationary hover. The difference would be CG location.

Yes and another reason why several similiar helicopters (Blade SR) could all lean at different angles..

The motor / Pitch variations..

Eg one model might be hovering with 1800 Rpm and 5 degrees of pitch

The other might be using 2000 rpm and 4 degrees of pitch..

It each case there would be a difference in the torque turning the rotors, therefore requiring different power from the tail rotor and that in turn would lead to more or less lean to compensate...

In Idle up on the SR you can trim the RPM with the small knob on the top of the transmitter.. if these were in different positions between helis it would easily explain the different leaning..
