What is the difference between Original software and community edition of Mongo DB?

Quixy recommends 'Percona MongoDB', instead 'Mongo DB community'. Here is the comparison between 'MongoDB community', 'MongoDB Enterprise', 'Percona MongoDB'. https://www.percona.com/software/mongodb/feature-comparison.

1. MongoDB community will have limited features and it's free to use
2. MongoDB enterprise has enterprise grade features and license is costly (per server / per core model)
3. Percona MongoDB is free provided by Percona community. 
   1. It offers all the features and benefits of MongoDB Community Edition, plus additional enterprise-grade functionality. 
   2. Optionally, we can opt server level support from Percona
