Hey there, let's break this down clearly—this is a super common question when building map-centric apps, so you're not stuck parsing conflicting info alone. Let’s compare the two tools on the metrics that matter most for your use case: core functionality, performance, and fit with your goals.

Core Functionality Matchup #

Your app’s key needs are Mapbox map display, layer switching, and interactive data visualization—both libraries can handle these, but how they execute differs significantly:

• Layer Switching:
  • Mapbox GL JS natively supports seamless switching between vector and raster layers, with full control over styling via the Mapbox Style Specification. You can tweak everything from line widths to fill colors dynamically without extra plugins.
  • Leaflet can handle layer switching too, but vector layer support requires plugins like leaflet-mapbox-gl or Leaflet.VectorGrid. It works, but adds extra setup steps compared to Mapbox GL’s out-of-the-box vector support.
• Interactive Data Display:
  • Mapbox GL JS shines here. It’s built for vector data, so you can easily add hover effects, click events on individual map features, or filter data based on attributes using its built-in expression system. No extra tools needed for most common interactive tasks.
  • Leaflet handles basic GeoJSON interactions well, but for complex vector data interactions (like highlighting thousands of features smoothly), you’ll need to rely on third-party plugins or switch to a Canvas/WebGL renderer, which adds complexity.

Performance Comparison #

This is where the two diverge the most, especially with vector maps:

• Vector Map Rendering:
  • Mapbox GL JS uses WebGL for hardware-accelerated rendering of vector tiles. This means zooming, panning, and redrawing complex maps feels smooth even on lower-end devices—vector data is rendered client-side, so it adapts perfectly to screen resolution.
  • Leaflet’s default renderer is DOM-based, which works great for raster tiles but struggles with large vector datasets. While plugins can add WebGL support, it’s not as optimized as Mapbox GL’s native implementation, leading to potential lag with complex vector layers.
• Large Data Handling:
  • Mapbox GL JS is designed to handle big vector tile datasets efficiently. It only loads the data needed for the current viewport, and WebGL ensures even thousands of features render without stuttering.
  • Leaflet can handle large datasets, but you’ll need to implement extra optimizations (like clustering or server-side tile filtering) to avoid performance hits—something Mapbox GL does automatically.

When to Choose Which? #

Go with Mapbox GL JS if: #

• Your core focus is on Mapbox-hosted vector maps and you want a streamlined, native experience
• You need advanced vector styling or complex interactive data visualization (like dynamic feature highlighting based on user input)
• Performance with large/complex maps is a top priority

Stick with Leaflet if: #

• You need to support multiple map providers (not just Mapbox—e.g., OpenStreetMap, Google Maps)
• Your project relies heavily on the huge ecosystem of Leaflet plugins (like custom markers, measurement tools, or specialized overlays)
• Your team is already deeply familiar with Leaflet’s workflow and you want to avoid a learning curve

Final Takeaway #

Mapbox GL JS absolutely matches (and often exceeds) Leaflet’s capabilities when it comes to Mapbox-specific map apps, especially for vector-focused use cases. The conflicting online info likely comes from folks who haven’t explored Mapbox GL’s full feature set, or who rely on Leaflet’s broader plugin ecosystem for non-Mapbox tasks.

If your app is centered on Mapbox maps, layer switching, and interactive data display, Mapbox GL JS is a robust, high-performance choice that will serve you well.
