Personally, I picked a veiled because of where I live. I'm in the high desert, and wanted to keep my chameleon in the living room. Ihave high ceilings, and there is no way to keep the humidity up as high as I would think a panther would do well at.
I also knew that an automatic misting system wasn't something I could handle in terms of the technology. ( a lamp timer was a challenge, and let's not talk about the computer!)
But I knew that between my daughter and I we could mist at lleast three times a day, and have the needed income and savings to deal with any unexpected costs (vet bills, the cost of silkworms...!)
I think the most important thing is to look at your lifestyle, and be honest with yourself about what you can and cannot do.
