Consider the below examples:

Some things are easier to read than others. Consider the following

    if x == 4
        # do work
    elsif x == 5
        # do work
    elsif x == 3
        # do work
    elsif x == 2
        # do work
    elseif x == 12
        # do work
    end

Now compare the above to the following:

    case x
    when 2
        # do work
    when 3
        # do work
    when 4
        # do work
    when 5
        # do work
    when 12
        # do work
    end

What do you find easier to read?

Case statements are often easier because there is slightly less mental effort involved. And the less you have to think, then the better. KISS: https://en.wikipedia.org/wiki/KISS_principle. In my opinion case statements work wonders, because you don’t have to think about equalities - it’s implicit in its function.
