For a given size magnet, strength and temperature resistance can vary depending on the magnetic material. The easiest way to compare magnets is by their Pull Strength, or how much they can lift. Pull strength is influenced by Maximum Energy Product and Flux Density—for both of these, a higher number indicates a stronger magnet.

Maximum Energy Product is the stored energy in a magnetic material.

Flux Density is the magnetic field concentration at the surface of the magnet.
