So I should buy the 150/1200, am I correct?
...with the same eyepiece ... YES ... (mag = fl of scope / fl of eyepice)

But the Maximum amount of practical magnification is a factor of (up to) twice the aperture (in ideal seeing conditions), and assuming you can obtain appropriate eyepieces, then this will approximate the same on the two scopes.

In that respect, quality of image (as discussed by Kunama ) comes into the equation.

Additionally, the sheer size of the scope may effect yoou decision based on mobility.
