It depends, I have a CH parson's but I hear WC can be very difficult. A lot don't have success with the WC's. They do not handle change well. An enclosure change, or setting change seems to put them in a funk for a few weeks IME. They can be picky eaters, get huge, need a large variety of large feeders when they're older, tons of water, montane requirements, and brumate during winter months.
I'd say with proper research, a huge space(most keepers have them in custom small room sized enclosures, tons of water(mine gets around an hour of misting a day), and some good outside time that they're not too difficult. It's like keeping a montane chameleon, but just everything you need is more and larger.
