@nprofile1q... I never used this one because I realized they hadn't implemented the software fastpath for... I think it was 4in6 tunneling? And that would've meant no line rate 1G routing for my internet...
The ER-X is more of an L3 switch in that regard and can handle the fastpath in some kind of configurable hardware thing including the 4in6. It was my main home router for many years until I moved and upgraded to 10G ^^
