It’s very common for 110v circuits to suffer from voltage loss during peak demand, and starve the motor for amperage. 220v is much less likely to suffer from voltage loss, so the motor tends to start faster, and recover faster from lugging….it also tends to run cooler. If your 110v circuit is at all suspect, you might find that 220v makes a noticeable difference….not more horsepower, but faster starts and faster recovery can make it seem like it had it’s Wheaties. 220v can be handy to have for bigger motors, even if you don’t notice a difference on your TS.
