Learn English – Idiom for choosing between two generally alike things that are dissimilar in their details

idiom-requests

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.
