I am confused because I don't seem to find the right idiom, for example:
I have to choose between two things that are generally alike but dissimilar with respect to details.
I have to choose between two scientists (they are alike as they are both scientists) that worked on 2 different topics (thus making them dissimilar).
Which idiom do I use? What I am looking for is an idiom that is the exact opposite of "between the devil and the deep sea."
It was on the tip of my tongue. Please help.
