I have a couple of mirrorless cameras and a variety of lenses. And even other Point & Shoot compact cameras. But I still use the SX50 on lots of occasions.
My main uses are for wildlife. I could use a very long lens on my mirrorless (and I have a 600mm equivalent), but to get max quality you'd spend thousands. I find the SX50 to be a great compromise when I need a very long zoom, and of course it's far easier to use, less weight, and is cheaper than even the budget mirrored superzoom telephotos.
Plus the SX50 has many of the manual controls I'm used to on more expensive cameras, a viewfinder (essential for outside work, but not as good as you'd find on an EOS eg), and a nice articulated screen, handy for macros.
Capture time with RAWs rather lags, but is expected with a compact camera. But video is good, and autofocus decent. Prefocus helps. Rapid fire shooting for bracketing is also slow, but acceptable once you account for it.
It has good battery performance, and the controls are easy to use. Zoom is occasionally a bit choppy, more so than manual on a DSLR, but the motorized feature to zoom out to frame and then back in is very handy at long focal lengths.
All in all a great travel and outdoor enthusiast's camera.
