I truly appreciate this! This is incredible! I'm on Comcast's 1,000/35 plan, and this seems to have helped quite a bit. It seems I needed to lower the quantum and limit to around 2400 instead of 3000. I only did one test each, so some of this may be margin of error.

Here's my results from https://www.waveform.com/tools/bufferbloat:

Before
Unloaded Latency: 13ms
Download Active Latency: +33ms
Upload Active Latency: +6ms
Down: 636.3mbps
Up: 44.9mbps

3000/3000
Unloaded Latency: 11ms
Download Active Latency: +27ms
Upload Active Latency: +1ms
Down: 725.2mbps
Up: 39.4mbps

2175/2175
Unloaded Latency: 12ms
Download Active Latency: +10ms
Upload Active Latency: +4ms
Down: 790.0mbps
Up: 38.8mbps

2400/2400
Unloaded Latency: 12ms
Download Active Latency: +7ms
Upload Active Latency: +4ms
Down: 777.6mbps
Up: 40.1mbps

Hardware:
- Motorola SB8600 (using single gigabit WAN)
- SuperMicro mobo, i3 7300, 16gb DDR4 ECC RAM.
- Using both onboard NICs, one as WAN, one as LAN.
- TP-Link 8-port gigabit switch between this PC and OPNsense

EDIT: Getting better results leaving the quantum and limit blank, and reducing the down pipe to 900mbps.
Bufferbloat Grade: A+
Unloaded Latency: 13ms
Download Active Latency: +4ms
Upload Active Latency: +0ms
Down: 889.5mbps
Up: 38.6mbps
