Color editing is at the top, and since version 12…14 it also has very good full non-linear editing. It is also cross platform (even a Linux version). Interface is adaptable and has presets to look like Premiere, Final Cut or Avid, if you are accustomed with those. Version 14 has a "live save" option that continually saves the project, so you don't lose work if it crashes. But you can also use the time-based auto-save, of you are over cautious with overwriting files. You can get a free Studio license if you buy one of their hardware products (Blackmagic camera for example)
Learning curve is a bit steep, and sometimes it crashes suddenly, but it has auto-save. Noise reduction plugin is available only in paid version.
Download the free version 14 and try a test project – you'll love it straight away, even if it takes a while to learn. You can customize the interface to look like your previous editor, for easier transition. Even the paid Studio version is much cheaper than the competition.
Years ahead Adobe Premiere regarding color editing, and now on par as non linear editor. Price is a full-scale winner – there's a free version with no limits, and a Studio version at 300 USD, that has collaboration options, uses a dedicated relational database (PostgreSQL) for project storage and has some extra plugins. They also say that, once purchased, all updates and upgrades are free for life.
