I'm so far off the beaten path since I don't use photoshop or lightroom.
FastStone is the go-to editor for basic stuff... cropping, auto-adjust, highlights/shadows, USM sharpen/blur.
I've used Imagic 5.0 which has a few cool features some others don't. Free version available.
Paid versions I currently Use: DxO with Filmpacks (expensive but powerful RAW processing), Cyberlink PhotoDirector 5 (some unique patching features, stray object removal, not too expensive), OnOne Perfect Photo Suite 8 (love this).
No longer use Picasa or Microsoft Live Photo Gallery (both free and are decent but outgrew them)
For HDR stuff I use EasyHDR 3 which can do RAW or JPG's.
