I think it boils down to personal preference.
On one machine, that is shared, I have avast Free, and MBAM free which I (try to

) scan with regularly, and keep up with things on it.
On another, all I have is avast Free and Winpatrol Free.
I am comfortable with these setups, but given the option, I possibly would take the pro version of MBAM for the shared pc at least, but not having ever used MBAM pro, I can't really judge anything about it.
For me, the detections from each (while they may overlap, and cause some issues - understandable) are different. (for instance MBAM pro could stop some Rogues from installing before some AVs - that is the point of MBAM after all...)
For a lesser powered machine, the pro version of mbam in conjunction with an AV may not be the best option but the free version is still an option.
That's my opinion anyway...
Something else I want to add as a general thing to all here. What you use is your choice, based on your opinions. So insulting another user because their opinion differs, is completely uncalled for. Whether you agree or not. The whole point of this thread is to get a balanced view of everyone's opinions, not to call out each other on what they use.
Seeing loads of thread degenerate into users bickering back and forth at the moment...
