That depends which CS version do you have
For me CC have many cool improved stuff...from sharpening, blurring,...and so on...and sometimes I also do designs there, so the new guides help me a lot.
I recommend PS versions from CS6 above...well, because of backups which PS saves in the background. That can help a ton when your comp crashes or you run out of electricity...usually the file would be damaged, but newer PS versions recover them
