As WHS says it is up to you. I have system reserved on 2 PCs and no system reserved on a 3rd. It doesn't matter and my decision was quite whimsical since I don't use bitlocker.
Before you assume "MS know best" the system reserved at 100MB was not a good choice. Mine are 200MB for good reason. If you use Windows inbuilt imaging and a 100MB system reserved some users have run into trouble (shadow storage copy issues)
