I would say.... no?
I have an Ohana long neck soprano and I love it! I loved it so much that it inspired me to get an Opio long neck soprano and I loved it as well. Unfortunately it had a build issue which was covered by their warranty so I asked that I get a long neck soprano to replace it. At the time they didn't have any and didn't anticipate having any soon so they offered me a concert to replace it which is what I have now. I love it as well. Both played and sounded excellent and the difference in sound between the soprano body and concert body is more like something you would be searching for than something that really stands out. It's kind of like potato chips with different flavors. Both are excellent and enjoyable, it just comes down to choosing what flavor you would prefer. I don't think you'd be disappointed with either so if finances are a big factor, I wouldn't be afraid of taking the long neck.
