to Put the Netduma brand on top of all Router types, for myself i think that you should add a way to switch different qos types (fq_codel, hfq, cake etc).
Right now the only other Router types are based on OpenDD and/or OpenWRT. Dont get me wrong, right now with the early Access the R2 get better and better, but (for me) CoD works better If you switch settings every few days. Some days QoS 70/70 are better, some days 5/5, some days disabled, some days Geo Filter on/Off etc. There also days where my AiO Router with his Hidden QoS Type works best.
+1 If you implement a switch for QoS!
