Comparing players over 1 season is a fools errand. Career - wButler's platoon splits are nothing to worry about, Lind is a pure platoon bat, but admittedly better against RHP. Butler strikes out less, and walks more, has similar but slightly less power, they're a wash defensively since both are pretty bad, but since both would be DH the vast majority of the time, that's really not a concern.
Overall Butler is far more consistant, and the contracts are similar. Plus since you could DH Butler every day and stick at 1b to give Edwin a day off or two, you wouldn't have to worry about finding a lefty killer platoon bat which would allow for additional flexibility on the bench.
If you can find Lind a legit lefty masher with real defensive usefullness, then yeah that's fine. But if you just compare 1 player to the other Butler is the better option all day, every day
