Comparing differences between CucumberStudio and Cucumber for JIRA

Hi,

I'm currently looking at CucumberStudio and Cucumber for JIRA as potential tools to introduce to our teams and would like to know the following:

1) What are the functional differences between ‘CucumberStudio’ and ‘Cucumber for JIRA’? Is it simply the former is its own independent application while the latter is a jira plugin?

2) Do both maintain synchronisation between feature files <-> git or only one of them? how does it work exactly and are there any limitations?

3) What new issues types does ‘Cucumber for JIRA’ introduce into JIRA?

Appreciate your assistance, thanks.
