Okay, so I just found that there are conflicting optimizations between these two softwares. (Applying the optimization on Razer will make IObit optimization status as "unoptimized" vice versa)
They point out exact same settings which in my case were 3 (see screenshots for the setting names).
I tried to apply both optimizations to my system to see the results. Surprisingly IObit Advanced SystemCare made my system more responsive and boot up faster as opposed to Razer which does the opposite. So that's why i am posting here If someone has the same result as me or is it just me that encounters this kind of problem.
I don't know if these two companies are still related to each other particularly in this, but I know that the old Razer Game booster before it was integrated into Razer cortex which is now System Booster was or based from IObit's own game booster. If yes then i'm not sure why do they have different configurations.
If someone can test this go post your result in the comments or in the poll, it would be highly appreciated and would help the community and possibly the developers will notice it. Thanks.
Here are the screenshots for the conflicting settings. IObit marked them as "Unoptimized" and Razer "Not Optimized"
