Oof i just dont know. the video you gave me before i didnt understand because i couldnt see from that angle. I like videos that explain in picture and show me how it looks like when you do it.ZBF2L is objectively easier than regular OLL, as you don't need to inspect a single edge on the outer U layer, and the algorithms are very short. You only need to look at the top face for a brief moment. Here are a couple of examples of how much more efficient it is than 4LLL.

Compare this very common ZBF2L + OLL case to a 4LLL solution.

ZBF2L:

Insert pair:R B U' B' R'

OLL:R U R' U R U2 R'

Move count : 12

Once you practice enough, you'll notice that this ZBF2L case also cancels into the OLL bringing the Move count down to just10.

4LLL:

Insert pair:(R U' R')

Orient edges:U' f R U R' U' f'

OLL:U R U R' U R U2 R'

Move count : 18

Assuming you're a beginner, those U moves are necessary since you're not accustomed to performing algorithms from alternative angles.

Let's take a look at another case which is pretty dreadful.

0 oriented edges.

ZBF2L:

Insert pair:U' y' R' F' R U2 L R' F' L' R

OLL:R U R' U R U2 R'

Move count : 17 -- Cancelling the final R of ZBF2L into R2 on the OLL brings it down to just17.

4LLL:

Insert pair:(R U' R')

Orient edges:F R U R' U' F' , f R U R' U' f'

OLL:B' R B L' B' R' B L

Move count : 23

Again, if you need some help, let me know.

You just need to commit to repetitively solving the cases.

Apply the inverse of the ZBF2L case to your alg, then solve it. do it 10-15 times, then try another case. That's just the hard but necessary path of learning algs. Another fast way you can practice is just scramble using R and U moves and throw in a F R F' once in a while to flip some edges. This way you can skip half of your solve and work on ZBF2L effectively.

ZBF2L is probably better but i only really understand from a perspective where i can see what is going on. Algs dont really capture that feeling

You could probably make a video with a camera on your shoulder or something like that so i can see but you are probably annoyed by now.
