Choose by workflow
Think about how your team builds levels. Some teams start with simple shapes. Others begin with terrain or tile maps.
If you need quick playable tests, use an engine with in-scene editing. Unity and Unreal Engine support this kind of work. If you need a dedicated 2D map editor, Tiled or LDtk may fit better.
Check export and engine support
A level editor must fit your game engine. Check its export formats before you build a large project. Also confirm that your engine can read custom object data and map information.
Test a small level before you commit. Import it into your game. Check collision, scale, materials, lighting, and gameplay objects. This simple test can prevent costly changes later.
Think about the whole production cost
A free tool may still need extra software and setup. A paid tool may save time in a larger production. Compare the full workflow rather than the license price alone.
