I use both Avast and Avira Anti-Virus; along with MBAM/MBAE, and some other goodies.
Like asking about Chevy, Ford, Toyota, KIA, etc. -- what kind of "look and feel" and overall operations is pretty much personal preferences. AV/AM ratings are like horse races, #1 #2 #3 positions will differ as time passes.
And if you need that many programs none are as effective as other single software options available that offer better protections! When they say "multiple layers" that doesn't mean you are required to run multiple programs! What that refers to is how effective is what you are running along with following the "Common Sense" approach to things!
The best software protections seen now are full featured Internet Security type suits several av software companies offer. Different review sites will of course offer different end results depending on which programs are being compared. Web filitering comes into play the most since no matter which search engine you prefer you can still get nailed with some type of malware or virus if not having safeguards in place such as web filters which tend to block out suspect sites as well as flag suspicious coding on any downloads! A working and effective firewall also helps when downloads like utility apps have unwanted extras being flagged and quarantines by an effective av software!
