@ Sachin,
1> Package version, build info tell you what you have in each environment.
2> External tools - Adding notepad++
3> Other option is to think of writing a utility service (may be a solution) something called "Package Comparator" that would compare packages on different IS and lets you see the report. But again you have to invest time for (solution)design, approach and coding…
Think what is good for you at the moment. Let me know if you have questions we can discuss further on this.
