damn @Malware Test , you are the one who does lots of antivirus review and people actually take advice from you
Anyway
My opinion is if you are not facing any probllem with 360 TS then no need to change.
Bitdefender is heavy whereas AVG is little bit less secured.
I would stay away from AVG to be honest. AVG have a poor detection rate in my opinion, is buggy, causes a lot of Windows related issues (slowness included) and it comes bundled with a spyware (their AVG SecureSearch Toolbar, look it up). Also, AVG PC Tune Up is one of the worst piece of software there is. The only way it actually increase your system performance, is when you uninstall it. Not even joking.
tl;dr version : Stay away from AVG products, they aren't worth it at all. Also, Bitdefender is good, the only issue is that it's an heavy resources consumption Antivirus in my opinion. I would rather pay for a Kaspersky or a ESET product (ESET if you want to keep your resources, their products uses around 200-300MBs less RAM than Kaspersky's products).
But that's just my opinion.
