What workout splits do you all recommend?

So my current workout split is -
Day 1 - chest + back
Day 2 - legs
Day 3 - shoulders + arms
Rest for one day and then repeat.

The issue I’m having is on day 1, once I’ve done my chest exercises I feel too fatigued to do my back exercises to the best I can so my back development is starting to lack. The reason I went to this split was so I could have a specific shoulder day because again, they’re a weak point for me.

I was thinking something like this split -
Day 1 - back + shoulders
Day 2 - legs
Day 3 - chest + arms

Would this be a bad split, if so why? I moved away from the typical PPL because of the lack of shoulder volume but would love to know what you are all doing and finding is working.
