All headlamps tend to suck when stock.
Anyway, that’s my opinion.
Beams are too narrow / not floody enough.
I don’t know about the Zebralights, they have ‘mules’ too, with a diffused lens.
But they cost too much money for me.

I have a cheap headlamp with 2x 18650 on the back of my head and it has USB charging.
Lasts very long, since i use approximately 1 Watt of power.
Nichia 219C 4000K 90CRI and a 120° TIR optic which i frosted additionally.

I have a small 14500 headlamp too, with the same LED, only 1 mode (just a single 7135 as a driver, so it’s approximately 1 Watt) and the same optic.
The little one only lasts about 2 hours on a freshly charged 14500, though.

So very wide beams with a bit more intensity in the middle.
Ideal for small stuff DIY and other close up jobs.
Low cost lights.
Far from stock though, so i recommend my set up only to modders and (re)builders.

Maybe the best affordable stock option would be the Skilhunt H03.
But i would need a high CRI LED and a wider optic.
Wider optic (only up to 60° unfortunately) can be bought here:

This is the very optic Skilhunt uses by the way, so it’s an easy swap.
You need T4 torx to take the bezel off.

It does depend on your nose too, though.
It’s very annoying when the light shines on your nose.
It (your nose) will dominate your view when it’s lit up.
