求问关于UCSD CSE PhD Program下CE和CS的区别

大家好！在UCSD CSE Department下的PhD Program里，只看到了官网介绍这么一句区别：

What's the difference between a degree in Computer Science vs. Computer Engineering?
The main difference is the wording you'd like printed on your final diploma. Although we allow research specializations in many topics, you will only be presented with a diploma in Computer Science or Computer Engineering. Please select the one you'd like when you are applying. If you need to edit your selection, you will be able to do so after you have been offered admission.

. Χ想问一下各位过来人CSE下的CS和CE除了degree上的名字还有其他层面有区别吗？例如选课；
以及还想请问一下这两个方向录取难度如何，一个department的两个方向难道是分track录的吗？？
