If we’re talking groundstrokes without using the wall I prefer open stance without rotation myself. Pros and cons to either, depends what you’re comfortable with.
Little edit with more context: balls to the body are usually played as backhands. If you play open stance you ‘ll have more angles from the same preparation, as well as lobs and chiquitas. That’s the main advantage though the stroke is harder to execute. If you step aside into closed stance you can drive the same ball with more power, but lobbing or playing an angle will be a little harder to disguise.
Even when you have time to move sideways ?
Often, I prefer open stance for groundstrokes. Easier to steal time from the opponent. If I have that much time I might even step in and volley the ball instead. It's very situational though. It might also be better to run around it and prepare for a big forehand.
And just pushing the ball infront I suppose?
Depends on the quality of their ball. Short balls that don’t make you move are often easy to attack.
