Compared to lightroom 4.... it's quite a kettle of fish. There's a LOT of differences between the two systems.
For most photographers, lightroom 4 gives an easier to use, better cataloguing system and a wider range of simpler adjustment tools. For commercial photographers, tethering in C1 is unparalleled, the C1 raw converter is superior to the adobe ones, etcetc. It is, however, more technical, can be a bit of a pain to work with, etc.
Certainly don't view it as a 'cheap alternative to lightroom' as it's a far more advanced bit of software.
