AG MV3 likely offers 99.8% of the features provided by uBo.
For example, in the syntax of adGuard rules,including MV2,there is no scriptlet feature identical to “Nostif” in uBo.
Furthermore, ad-Flickers must also be taken into account.
AG MV3 is the heaviest extension; at least on less powerful PCs (like mine), it causes significant ad-Flickering, especially when using hidden filtering via custom rules.
UBlock Stripped - Dynamic Filtering, when compared to a set of MV3 extensions, is the one that performs best in terms of ad-Flickering.
Users of Brave + AdShield-Extra-Power-Tools fare even better.
In this case, ad-Flickers are reduced to 0 because Brave AdShields does not have the limitations of the MV3 extensions.
When using UBlock Stripped - Dynamic Filtering, to put it mathematically, it approaches,depending on the case,the limit of 0.
