I have both... but let me say this:
If you are [overly] confident in your skills and you want the challenge of owning a WC and trying to "break" it (horse term break). Then by all means get a WC. Note, however, you can't get a true WC panther unless its second hand. Otherwise the WC chams come from a "cash crop" population in my neck of the woods - which evoled from minimal Gene's etc, thus it's not truly a WC.
There's a whole realm of specific just for a WC, most commonly; many carry parasites (which curing can actually cause more issues and stress), the need for a bigger enclosure and more hiding spots, WAY less handling (and you probably are going to want at least one glove).
Most people get a WC cham for "new blood" for breeding. Some get them for the challenge. If you want a pet, get a captive bred/hatched. If you want a headache, heartache, and a cold shoulder, go for a WC.
