I like that it's easy to use, have several ways for my data analysis workflows are setup with multiple options available (from RStudio through Python). It also has great support from their team if you need help figuring something out or just want some advice about what features would be best suited towards your needs! There isn't much in terms of downsides but other than having an easier way set up certain tools/workflow steps there really aren’t many cons at this point either :) Highly recommend using them as they provide excellent customer service which makes things so smooth during our project implementation process - we used nimbus mainly because one option was more suitable then another depending upon who will do each step within workflow flowcharting etc., however once implemented everything worked seamlessly together providing us all access via dropbox folders where users could upload files without needing FTP connections directly into server environment / folder structure allowing.
