When Adobe switched to subscription only, I switched from Lightroom to C1 and never looked back. It is a steep learning curve, but there are plenty tutorials available on the web. I skip 1 version between updatges, which makes it about as expensive as an Lightroon subscription. RAW conversion is very good, and it uses layers which is a great bonus. Catalog is OK. I use Sessions a lot when photographing tethered. Latest version also offers easy stitching facilities and HDR, all in one package.
Highly recommende if you are prepared to invest some time in it.
