I love that it is so intuitive to use! It's very customizable (I've been able create my own animations!).
If you are looking for an easy way of building out interactive experiences without writing code then this library can help with your needs!! Honestly though - there isn't much else about sequence which makes me dislike using their toolkit as opposed to any specific feature or aspect in particular; however if we were required by our clients/clients' requirements than i guess one could say they have more features but those would be client driven rather than what was available when designing sequences initially :) We used Sequences js primarily because its ease at allowing us complete control over how each element transitions from state --> nextState--> previous State etc..
