What do you like best?
Two great things about EndNote:
1. Citations and notes can be combined into one file, so everything is available in one convenient place, even if I'm returning to a research project after months (or years!). I don't have to go hunting for things on my computer.
2. Easy integration with Word. The citation feature within Word works well, even for lengthy documents, and makes organizing citations very straightforward.
What do you dislike?
Probably the biggest downside of EndNote is simply that it's expensive, and there are various free options our there that do similar things. That said, if your university sponsors this (or you can get it reimbursed), I think it's well worth the money.
Recommendations to others considering the product
To be most useful, I would recommend committing to doing all your citations through EndNote. It's a larger start-up cost, but once you get going it really is much more useful this way. You can use "Groups" to categorize citations for use in different research projects

Organizing citations and notes; properly and efficiently citing material in working papers and published research.
