Hey guys

a bit of backstory:
our school's planes got destroyed some 4months back due to ridiculously strong winds ripping them off the ground and throwing them into each other. The planes were secured and all, but the winds were so strong that it ripped them right off.. They even managed to throw some of those airline containers from inside the airport to the parking lot of the airport.
So we finally got a new plane 2 weeks back and everyone is real happy.
We had an old 1969 172 and now we have a new 2004 172 to take its place.

So I went back for a re-familiarization flight with the new plane since it had been a while, and new plane, new gizmos, etc..

Now all the FIs were raving as to how great the new plane is, and how responsive it is and it is so much better than the old one. Here is the problem: I disagree with them
I feel it is LESS responsive and as a result more difficult to fly.
I'm having trouble flying it leveled almost.
Also I have a new instructor who seems to hate his job and probably thinks I'm horrible at flying. (old instructor quit 2months ago)

It isn't that I haven't flown in a long time, I was in the left seat of an acrobatic Marchetti in a "Fighter Pilot for a day" thing 1 month ago and I was smooth, level flight, perfect turns, and felt extremely comfortable.. kind of like riding a bike...

I just feel uncomfortable in this new C172. Like everything is wrong.

What could be wrong with me? I seem to be the only one who has a problem with this plane.. I used to be one of the best students at our school with the old plane...

just looking for some feedback if anyone knows what could be wrong
I'm willing to take whatever steps I need to correct this... I asked my new instructor, but he's just convinced I'm horrible and is not helpful at all.. He's given up on me after my 2nd flight with him.
