One thing I have noticed so far in my experience is the larger the fuselage, the heavier the feeling of the controls.
Have flown B737-200 & -300, B747-400, B757-200 and B767-300ER, honestly can't say there was a whole lot of difference! The B747 is a big, refined lady but control forces never seemed proportional to her size!
Never trimmed in steep turns, releasing the back pressure as the bank came off was, during my training sessions, the 'norm'.
