I have found so many of the rhizomatous rexs to be difficult, others are a piece of cake. That is what I meant by different cultural requirements. The pots can be right next to each other and receive the same water, food and light and one will keel over and the other will thrive. I too generally find the canes easier.
You can see some of the various types on these sites.
