I agree with snoop dog,

Although Cubs are nice and slow, and give a pilot plenty of time to think, there is plenty to think about. They have a flat bottom wing which makes them respond to every little gust and bump. Gust and bumps tend to alter the planes course and attitude when landing. And they require a bit of coordination of the rudder and aileron to fly. They are fun to fly. But they are deceptively difficult to fly.

Airplanes like Avistar, although they land at a higher speed, have a wonderful semi-symetrical wing that makes the plane more stable in a windy condition. You have less time to think, but there is much less to think about.

That is the trade off. Time to think vs. how much to think about.

I Cub will require authoritative inputs all the way to the ground. Newbies will have no room for error.

An Avistar is more or less set up for the approach and then almost monitored with small corrections when landing.

As you start learnig to fly, you will learn that the biggest and most important trick that you will learn, is landing.
And landing isn't achieved in the manor that many people think. You don't chop the power and glide her in.
You will learn that the elevator is used to control the pitch attitude of the airplane which essentially means its airspeed.
Rate of desent is controlled with throttle.
Sometimes a faster and heavier plane may be prefered, at least by experience flyers and they will find such an airplane actually easier to land. However, they have achieved a hand to eye coordination or a muscle memory reflex that makes landing much easier. The new pilot must overcome the lack of such reflex response by actually observing the planes actions, then actually thinking about it , anylizing it, decided what the correct response is, and then getting thier hands to do it.
For a seasoned pilot, he seems to simply think what he wants to happen and it does. It is as if the plane were connected straight into his brain.
Acheiving this requires simple repetition or practice. The question is simply what airplane will most likely survive this period in the fledgling pilots early hours, when he cannot rely on an automatic response.
Another dissadvantage faced by the new pilot is "planning". A seasoned pilot is not so completely immersed in the task at hand at any given moment that he cannot plan his next few moves. The newbie is not "planing several moves ahead. You will hear the term, " I was way behind the airplane". That refers to the pilot being so overwelmed by the simple task of flying the plane that he had no spare capacity to plan his future moves. In fact he was chasing it.
Just for example, in the past I flew a twin engines arplane for anumber of years. Before take off, I would imagine in my mind, OK what if the left engine dies on take off, which way will I have to go, etc and then imagine the right engine failing. It only take a few seconds before departure to imagine what you will do. Once in the air, similar thoughts are constantly being formulated in regaurds to lining up for the next pass after this one etc.
I am telling you WAY MORE than you need to know. And I hope that this doesn't sound intimidating. Get an instructor. You will become aware of this skill set developing. It is easier than it sounds. But just be aware, it might seem different than what you expect.
