While bufferbloat is an issue it's not the only one. Poorly designed NAT implementations easily suffer from connection tracking table saturation due to the many socket endpoint pairs they have to track when you're using bittorrent. Doubly so when using bitrorent with DHT.
The best thing to do is avoid home networking equipment entirely. The Ubiquiti EdgeRouter products are cheap and good, as is building your own router and sticking Linux/*BSD/derivative distros on it.
