I've found it a bit like "what car did you drive in to work with today" in that any typical current and working car is not going to be a stark difference to a high end car in terms of how fast you get there... but you'd definitely notice a piece of crap with a donut, broken heating, and screeching brakes causing you problems if that's what you were comparing instead.

I.e. I can count the number of times I said "wow, uBO Lite didn't make this site usable but loading up Firefox with uBO and it worked fine" on one hand. At the same time, if I ever look and compare how much is actually getting blocked, uBO is definitely blocking way more. Doing a side by side compare of dozens of sites it becomes easier to see minor differences I wouldn't otherwise have noted, but may not have mattered as much.

I commented about this a few weeks ago here about this, but essentially: v2 allows you to block things you can't see, but you still probably don't want, like folks hiding cloud analytics behind CNAME cloaking to allow it to appear as a first-party site rather than Google Analytics, for example.

You won't "feel" this in your day-to-day browsing, but if you're concerned about your data being collected, v2 matters.

Does it not still suck at blocking YouTube video ads? As in, you get a delay before videos start playing.

There are a lot more Manifest V2 only extensions than only Adblockers.

How's that work for you on Android? Firefox on Android with uBlock is the huge win.

Doesn't work for Prime Video ads. Tbh I don't mind that too much.
