That's just my experience.I have both t-9 and cutter. I always use my Cutter. If you are a horrible pilot, you may have problems flying it but I notiiced no problems at all. It does not require any special training. If you are attentive and a good pilot already, there is noting special about a cutter. It has a some drift if you try to fly it like a small ship. But if you are trying to fly that way, you're a bad pilot anyway, so you get what you get. I can manually land on any planet or station. I don't understand the "difficulty." that people talk about. It's big, but pure fun to fly.
Normally when I'm flying with a medium or small ship (and, to some extent, even with the Type-9), if I'm approaching a space port from behind or from the side, I just boost towards the front to get there as fast as possible, then turn the ship to face the mail slot, and make a nice curved fly path towards it. If my speed was excessively high and I didn't slow down soon enough, I might wait a bit for the ship to slow down enough and then correct and proceed towards the mail slot.
But the Cutter doesn't behave like that! When I did what I have always done, it just keeps on going, and going, and going, and doesn't seem to stop! Moreover, if I do what I usually do, ie. turn the ship to face the mail slot and fly towards it, while there's still lateral speed going on, the Cutter will just keep that lateral speed going on, and going on, and going on... and just doesn't stop. More than once I have collided with the station front wall because the ship just wouldn't stop. It just has a huge amount of inertia, and needs to be handled with care. You really need to start slowing down soon enough, or you'll overshoot the front of the station by a country mile (literally). It seems to have significantly more inertia than even a fully loaded Type-9 (no doubt because the Type-9 is so slow, so it doesn't build up even nearly as much momentum).
I was also caught be surprise the first dozen times I had to land on a surface construction site: While approaching the surface as I have always done with all other ships, the Cutter just keeps on going and doesn't stop! It literally behaves like when landing on a 2g planet, even when the planet actually has less than 0.5g.
One trick I quickly learned is that if I am accidentally approaching the surface too fast, I turn the ship to face directly up. That helps it stop quicker.
