WebBJT can handle a lot more current than MOSFETs. One of the reason why they are still in use is BiCMOS applications where basically CMOS part is used as the logic and BJTs are used to drive very high capacitance nodes. Other than that, they have very nice properties regarding their PN junction nature. WebSPICE simulation tools allow design engineers to validate circuits prior to building the circuits and to quickly test a circuit's likely behavior under a variety of conditions that can easily be modified.
