This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 2.0L I4 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the AMG GLC 43 if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the AMG GLC 63 S E PERFORMANCE only when the 2.0L I4 phev Turbo powertrain is the reason you are moving higher in the lineup.
