Thanks, Ewan.
I like DXO Photolab a lot more than Lightroom. However, if you keep it up to date, you're buying an upgrade every year and it doesn't really work out much cheaper than an Adobe subscription.
As a Canon user, I quite like Canon's own software - Digital Photo Professional. It's free... or rather 'included in the price of the camera'! It doesn't have all the 'bells & whistles' but it does get the most out of Canon lenses and it is the best for getting the correct colours from Canon cameras.
