Traditional transitors, or BJT or newer IGBT are devices which take input of current, meaning their function is current allowed at CE is = gain * Ibase. So are current devices, their output depends on a current input.
FETs input is purely voltage and their function is current allowed trough drain to source iDS = K/2 * (Vgs-Vth)^2. This function is now a curve and this has many implications. More important these are voltage devices, their output depends on a voltage input.
So imo traditional transistors and mosfets are quite fundamentally different.
