Back to the question in hand.
The PA28 will feel bigger, heavier and more solid in flight. Its also heavier to pull out the hangar! It doesn't suffer the nose wheel shimmy of the 152 when on the ground. The white arc extends further allowing higher speed flap settings, which can be very useful, particularly on the Archer. The fuel pump and tank change need memorising. You can not check the effects of the trimmer and rudder on the ground from inside as you can not see out the back. Sometimes, the door is a pain to latch and needs a jolt top and bottom to make sure it is shut properly.
There is far more room and space for all manner of things including your legs if you are tall. Hence, it feels more refined.
An hour of general handling stalls etc, followed by some circuits will do you to get the feel, speeds and settings sorted. You'll probably find that you'll never set foot in a 152 again if you're post PPL training.
