The only problems I might see with the 2 splits are:
In the first one, chest and shoulders might be to close to one another. Chest day uses a lot of shoulder as well.
In the second one, legs and back might be to close together. Leg day uses a lot of back in it.
If you are up for switching muscle groups that are worked together, this is a possible option as well:
Day 1: Chest/Back, 30 minutes PW cardio
Day 2: 60 minutes of morning cardio
Day 3: Arms/Abs, 30 minutes PW cardio
Day 4: 60 minutes of morning cardio
Day 5: Legs/Shoulders, 30 minutes PW cardio
Day 6: Off
Day 7: 60 minutes of morning cardio, Carb-up Day
This should give ample time between back/legs as well as chest/shoulders.
