Chill out, don't over think this.
Each Island has many nice attributes. Just make the mainland connections and fill in any one way travel. I have enjoyed all four islands over the years and have not been bored by revisiting them. We are returning to Maui later this summer for the first time in about six years.
Life is too short to worry about this kind of stuff. just know that you'll have a good time on whichever island(s) you choose!
