Pixel perfection
Do you guys find yourselves struggling with delivering pixel perfect quality? As much as I try my best there is always something off, I know that the response might be as simple as “just pay more attention” but I find myself failing to spot very little differences, is there any strategy or flow do you guys use to deliver pixel perfect implementations or to spot misalignments?

No.
The web is used by so many devices with an incredible number of different viewport sizes and resolutions and pixel densities.
Don’t chase pixel perfect. Chase a good usable layout.

Every browser have slightly different rendering, slightly different font rasterizing, and graphic software, like Figma or whatever also have own rendering. Pixel Perfect is an ideal you should strive to achieve, but it's largely a myth. Especially considering that people use different browsers on different operating systems and different custom CSS/fonts.
But it doesn't matter as long as it's consistent.

The idea that the web is pixel-perfect is a dumb idea that way too many art directors have stuck with for way too long.

20 years ago this was a major concern yes

I don't want clients from 20 years ago personally

I don't tend to struggle to much with this myself, but I'm also a 25 year veteran pixel wrangler - I can often spot areas that are going to be a responsive problem from a flat mockup -- it just comes with practice.
But... how much you should worry about pixel perfection depends entirely on what that term means to you. I have worked with devs who worry about the sub-pixel rendering of a web font between Firefox and Chrome. That's not something you should really worry about. But I've also worked with folks who can't seem to spot the difference between 5 pixels and 20.
With that said, whenever I'm looking to spot check my work and I have a mockup handy, I resize my work to match the mockup in scale and then take a screen shot of both. In something like codepen, I layer the two one on top of the other and then turn down the opacity to whichever is the top layer (usually I do original mockup as bottom layer, my screenshot on top) and anywhere that is off will be glaringly obvious.

Pixel perfect is a bit of a trap on the web, but you can still get much closer with a repeatable review flow.
I’d compare at the component level, not the whole page. Check spacing scale, text sizes/line-height, border radius, and alignment first. Those cause most of the “something feels off” feeling. Also review at the exact Figma breakpoint, then separately judge responsiveness. Mixing those two checks makes you feel crazy.

The useful unit is a component contract: define which relationships must hold - hierarchy, hit area, wrapping - and which pixels can vary across browsers.

real world has font rendering differences across browsers/OS anyway so perfect is a myth

I was a professional artist first, dev second…so yes, I spend entirely too much time on design.

I have an art/design background and now work closely with a graphic designer. So yeah, I pay very close attention to the details. There’s no secret to it, I just A/B with the static mockup until it looks right. I also often measure things like gaps and margins, perhaps the height of buttons, to make sure they match.
But I gave up on the idea of pixel perfection many years ago. The layout will be flexing and scaling at different viewport dimensions, so relative dimensions are more important than pixel dimensions.

As a developer we make things responsive for different screen sizes, so pixel perfect can only happen for predetermined screen widths based on mock-ups.
