Point 1 is basically what your personal preference is. I prefer it opt out as this will lead to more people supporting websites with ads. (defaults matter, check out organ donor studies on this)

While I admit that ublock is faster, Adblock plus has much better integration and looks better. When it's installed it presents me with very few options and I'm basically good to go without changing and settings.

Additionally I use umatrix which covers and options abp does not,which helps abps speed to almost not matter anymore.

Lastly I would add that the latencies I've measured to be caused by Adblock plus fall almost into the region of "doesn't matter". What little benefit ublock has given me the Times I've tested it was barely worth it.

Purely by "it's faster" you should probably be using ed over any other editor right now since ed is objectively faster than any other POSIX editor. Or pretty much most editors.

>strictly

I'd refrain from using absolutes when making statements about personal opinion. It makes you look like a fool.

>no advantages

As stated earlier, abp has much better integration. It's one advantage vs one advantage.

Seems like personal choice to me.
