I don't believe you'll find a clear answer, front end development is a fast moving world,
While people were happy with the simplification that jQuery offered a couple of years a go, now they realize that just simple code doesn't lead to a well structured application. Don't just believe me, but also one of the main developers of jQuery.

For an enterprise application I'd also look for a suite that offers several widgets/components that are known to work together. There might be a jQuery plugin for everything, but they're not guaranteed to work together. You might also want the same framework for desktop and mobile applications to reuse your developments.
- SAPUI5 is a possibility offering quite advanced features and an 'all in' approach.
- Dojo is not as known as jQuery but it too offers a complete approach with widgets.
For a larger project I'd inform about getting some front-end developers, see what their proposals are, because it is a lot of knowledge. A good one would not fix the framework used but look for the right solution to your concerns and budget.
