For me, it has its own advantages and disadvantages. If you are a pro user or an internet surfer that want the fastest connection ever, you may want to disable this ssl scanning features. I have tried Kaspersky Avast ESET Bitdefender, they impact the performance of the internet. But not for all especially if you have fast internet, this web surf experience will impact you lesser than people that have slower internet connection.
For the time being this features might not seems as important or must have feature, but with recently increasing compromised web, in the future, this features might be needed. Right now, im currently disable the ssl scanning. Besides its not perfect as they claimed it is, even some started acting weird like blocking google ssl or some legit website without any causes. But the technical team usually failed to recreate the situation which rarely happened.
