It just has the most pleasing tones I think.
Yes no dedicated attack is stupid but otherwise the simplicity of the Cycles is a strength. If you want to use the Elektron sequencer as a sound shaping tool, Models is the rawest most intuitive experience.
6 separate tracks instead of 4 makes a big difference imo. Weave all six of these together in a complementary fashion - no drums - and it is more than enough for lovely ambient soundscapes. A sum of its parts type mindset.
With a Digitone or other box a lot of procrastination can take hold imo. Cycles is more “go with the flow” - it plays you as much as you play it.
