Jose,
I will ask you nicely to please watch the use of terminology you are using here and I will ask you to show just a little bit more respect towards the other forum users around you.
To the topic starter: Unfortunately, you are going to get a million different answers! especially with the question you asked "how good is CIS compared to other products?" All in all, It's based on YOUR needs and your own testing of products to see what product(s) work best for you overall. People here will, and already have, basically stated that CIS is good just as package, or maybe get rid of the Antivirus and choose another Antivirus - It's really based on your own research and what's best for you as a user. Personally for me, CIS has worked just great by it self. But remember, other people will tell you opposite things so keep that in mind.
I tried to avoid your question because people will say to you "this product is better then CIS" and vice-versa so the question will start more trouble then advice unfortunately.
If you need anything else just ask please the community will be more than happy to assist you. 
Cheers,
Josh
oh I expected to get a million different answers, and the benefit of discussion lies in different answers and different opinions.
One of the amazing thing of forums is, to me, to benefit of various views of the different people who are participating.
In the end, sure I have to think myself to act with what I feel confident with. But taking in different opinions is always great, it helps me to think of things I would not have thought of myself in the first place.
And I know very well that there is no single product that gives 100% security, that was not the intention of the question. I just hoped to get some honest and balanced answers, and that I did get indeed, along with some more information

Now I did a few tests myself during the past days, with a freshly set up Windows 7 on my notebook, and because my PC is not infected, and hopefully will stay that way in the future, I just tested features, update behaviour, speed and such, and with the outcomes I am quite happy with CIS as a package. For the forseeable future I will use CIS as my Internet Security application, and in addition some on demand scanners too, like MBAM and also MSSE (deactivated, only for demand scanning).
With this setup, and my brain switched on while being online, I feel quite secure.
Thanks for all the answers
