Free Software I've used and liked: Darktable, RawTherapee (both are RAW converters)
Paid Software I've used: Corel Aftershot Pro. You pay once for the license and I would say it's very easy to use. Works well both for RAW and for JPEGs (the "Perfectly Clear" algorhythm is great for JPEGs too and is basically a one-click-enhances-your-photos kid of thing)
Paid or Subscription Software: Adobe Lightroom. I think you can still buy a one-time license. But a lot of people are on the subscription service because they get the latest updates that way. I haven't used it, but I think it's still the software most people use.
I'd second the vote for Aftershot Pro (current version is 3).
During initial setup, I had some issues with it crashing when importing a large number (70k) images; but I was able to work that out (long story short: it would consume all 16GB of RAM during the import process and crash when it ran out of memory. I re-enabled my page file and voila).
I wanted it for two purposes: 1. to ease the process of selecting and culling shots and 2. to be able to make batch adjustments to shots.
For item 1, it's quite good - you can use hotkeys to mark shots as keepers or trash, and use the number pad to assign a star rating. Using said hotkeys and the number keys to advance to the next shot, you can fly through a set. When you actually delete the shots you've marked, it's a little slow; but it's not a dealbreaker. And you can do side-by-side comparisons of shots (it syncs the zoom level and panning between the shots) to select the best one. It works a treat.
For item 2, it does everything I want it to do - the usual exposure, contrast, and color tweaks, as well as great black and white conversions and easy stacking of exposures. I'm not terribly advanced in this realm.
It ain't perfect; but given that it's a one-time cost and quite powerful, I'm pleased overall.
Oh, and I also had to jump on the K-3II deal from Adorama. The price for the silver was NUTS!
