Why are Carto basemaps more performant than Mapbox maps?

I'm following the icon tutorial for Deck.gl in React. I swapped out the MAP_STYLE from a Carto basemap, https://basemaps.cartocdn.com/gl/dark-matter-nolabels-gl-style/style.json, to a Mapbox basemap, mapbox://styles/mapbox/light-v9.

I've omitted much of the code, but here's the return function for reference:

  return (
      controller={{ dragRotate: false }}

The issue comes when I try to move around the map. When I use the Carto basemap, the movement is quite smooth, whereas there's a noticeable lag in the Mapbox basemap. Here are some gifs for illustration:

I want to use Mapbox since I find their layers more aesthetic, but I can't seem to make it as performant as some examples, such as this one.

Are there any additional optimizations that I could make to improve performance?

    For anyone who comes across the same issue, it seems the easiest fix is to export the style from the Mapbox style builder and import the theme as a JSON in your React project.
