no. for normal use, the existing devices are completely sufficient. i replaced an old router with them, which was worth it. however, your devices have enough "plug" so that you won't notice any speed difference. the security functions are the same, apart from any functions offered by a third-party provider in the ax11000. these are free, but if you use them, the device reports network traffic logs to the third party - or at least this is not excluded in the agbs to be accepted. but if you don't want to use these additional security features, you don't have to accept the agbs.
