I have always preferred Cub Simba. Adult Simba has never been a favourite character of mine.
Just a note about Kopa: In TLK6NA it is shown that Simba is too busy with his royal duties to spend much time with Kopa. In fact, Nala is the more protective parent! I believe that Nala realized being too protective and worry and fuss over your cub constantly is not going to do you or them any good. With Kiara, Nala had much the same parenting style as Sarafina, more relaxed, giving her daugter the trust and personal freedom she needs.
I believe that the loss of Kopa left both Simba and Nala devastated, but Simba is trying to make up for his mistakes with Kopa by being extremly protective of Kiara, to prevent the loss of another cub.
Although I completly understand Simbas need to protect his daughter, I always feel so sorry for Kiara... Not allowing her to hunt ever again is just idiotic.
