RE: cubs make good trainers??
If you want to learn to fly, I would suggest a Trike gear trainer made for that purpose. When you want to learn to take of and land tail draggers you can go with a cub or similar plane. I have taught people to fly on cub type planes but typically they go through several planes in the process. It doesn't make a lot of sense to go that route. Learn to control the plane first, on the take off, flight and landing then graduate to some thing a little more challenging. That's my observation after 30+ years in RC.. Good luck and get a qualified pilot to help you, regardless of what you choose.
