Recommend router and switch connected with private fiber

I got back to revisiting this.

Would it be better to use a L009 router (SFP) OR hEX refresh router and RB260GS (SFP)?

My last thought was a RB260GS at each end of the fibre, and a more standard/plain router at the internet.

But currently I’m looking at the L009UiGS-RM router, and that has the SFP on switch chip and eth1 on the CPU. Seems to match to our setup in that way (instead of most routers having SFP on the CPU hindering performance).

  • Ports: The L009 also has 8 ethernet ports, so effectively the same ports as hEX + RB260GS (since 2 are used to link them).
    Test results: L009 is a bit lower than the new hEX (although we’re probably not high demand anyway).
    MTBF: 200,000 for L009, vs 100,000 (so more robust/longer life??)
    RouterOS license: L009 is 5, while hEX is 4 (not sure the ramifications of that)
    L009 a little neater setup contained in one unit.
    Price works out about the same here.

Is there advantages to going with the two separate units? Significant performance differences or other issues one way or another?
