Alternative Bootstrap walker nav

I remember when the Bootstrap nav was removed in a recent update some people were mentioning in threads that there were better alternatives out there that they use for responsive mobile nav. Just wanted to see what else is out there that other people are using before I add back in the Bootstrap nav or decide to go with a custom option.

Thanks for any suggestions.
