Cons
Con Highly opinionated
JSLint has a very strict, dogmatic ruleset that cannot be changed or warnings turned off. So much so that rarely any code will pass JSLint tests. It's reasonable to evaluate if all warning are worth changing.

Con Difficult to know which rule is causing which error
Since you can't edit the rules and it's not programmed in a way to display the rule that's being broken, it's difficult to understand which rule has been broken.
Con No way to support ESnext
Con Bad tech support
Con It's NOT Open Source
You can't fix or, implement nothing. And when the developer abandons the project you will be left in the lurch.
Con It's not free
Nither as free price nor as free in freedom.
Con Cannot compare text within the same file
Sublimerge can only compare entire file diffs, but not two selections within a file. Comparing within files can be useful for example, by refactoring two similar functions to use a shared function. With Sublimerge, you need to copy the sections into two new temporary tabs and compare between the two. This can be cumbersome, as if you have another untitled file, you won't be able to know which one is which.
Con No version control integration
