Well for me it is simple as to why I use TSE over TS, namely because of four reasons ...
1) I do not need Patch Up because that is handled by Windows itself.
2) My WiFi is not recognized by TS, so that Security Check is of no use to me.
3) I do not need Clean Up, because I use CCLeaner and PrivaZer for that.
4) And Speed Up is to eager to advise to deactivate things I want to keep active.
Yeah I know I do not have to deactivate the things advised by Speed Up, but still. And yeah I know that TSE is at version 7.2.0.1027, while TS is at version 8.2.0.1098, but that does not matter to me. 360 TS is their most liked program because it is all in one, TSE has so far always been updated to the newer versions sooner or later after TS so far.
