WML or Handheld?

I know this question gets asked alot, but what are your realistic reasons for carrying a WML instead of a handheld?

I recently added the streamlight TLR-7 sub w/ an antimatter wing to my current EDC just to get a feel for it, but it’s hard to justify the extra oz and bulk to my appendix holster. The handheld light seems like the better choice but I would love to hear your thoughts.
