Until this year I've been using Lightroom extensively. I've now completely switched over to Capture One pro 7.
Why? Personally I find the results are just better and that bit counts. Some tools Capture One has like the colour correction tool (huge one), tethering tools and even the clarity/details sliders are a light year ahead of Adobe in my opinion. That said, I completely agree Capture One is built for commercial photographers. But that said, any photographer of any genre can obviously use it. It's a very very different program, Adobe Lightroom I'd suggest is much more user friendly to the casual's out there, costs less money too!
Without going into any real depths, those interested would pick up there's a free 30 day trial. Either program can create stunning results, it's a personal and potentially logistical choice for some. That's my view.
