Is there some expression for situations where you can conclude that a solution's advantages are the same as the disadvantages of alternative solutions?
If you want to be a bit verbose and humorous, you could just repeat the fact verbatim and put the sentence as if it was a clear example/counterexample.
Example: You sell your car and do all your traveling by bicycle. That is environmentally friendly and your personal health benefits. On the other hand, shopping and quick, long-distance mobility is limited.
So you could say:
On the one hand, I sold my car. On the other hand, I sold my car!
