I would have to say that would be very much an individual thing, I had a small plywood cat called an Elwood Junior which I started out with (I won't say learned to sail, as I still haven't really) and used for one season. I sold it to buy scuba gear and bought the AI even later, I will say I probably would not have bought the AI if I didn't have the cat before it. The cat sowed the seed for sailing and the AI has helped it flourish.
They are two completely different craft, the cat was something you had to work at for performance and once attained, was a rush. Forget it if the wind was under 8 knots, good fun from 10 knots to 18 and for me get off the water over that.
In 6 to 12 knot wind, the AI is more chilled out, just kicking back enjoying the ride, from 12 up to say 18 knots it starts to get a lot wetter and a little more exciting but you still don't have to work that hard (not like the cat at least), 18 to 25 knots (shhh... and over) the AI is a blast, very wet and always thinking and watching and working on the waves around you, good fun!!
Note: the AI is not built to be in those conditions and if you do use one in those conditions, you do so at your own risk and the risk of damaging your craft..
For me, I am more than happy with my AI but I would not compare it to a cat, as for a mono hull, well I have never sailed on one, The AI is quick and easy to set up for one person un-like the cat and I can only imagine that the TI would be the same compared to your mono hull, so you will definitely use it more. Will you enjoy it more ? Only you can answer that as it comes down to personal preference.
I doubt you won't enjoy it though
