Simple looking at the hub tests and improvement over these years:
G Data , Kaspersky, Trend
Reason: G data, Kaspersky --> maintain clean status against most of the tests we threw at it(I did a lot of nasty ground work especially with these both) , Modules are signature independent, Very good balanced protection, Fp's are minimal, Last but not least both of these guys have very good IT security background, Sound Knowledge and patents.
Trend: For the improvement it shown over these years, Cost effective, Does the job securely, Intelligent Pro active modules with signatures(mediocore though),
The above products are cost effective, provides optimum security level and not performance eaters> Satisfy all the requirements <
Removing G Data from the poll and introducing CARTOON Av's like Panda, Mcafee doesn't sound good
