It makes very positive comparisons between the CS100 and the aircraft it will be replacing, the Avro RJ100.

Ryanair reckon their 737 Max will deliver fuel savings alone of 16% versus the 738 as well as 8 extra 'free' seats. Over a typical airframe life of 20 to 30+ years, the savings from new generation aircraft are invariably several orders of magnitude greater.
It's called technological progress.
