Have been happy with stock LR3 when using sharp new single flute upcut bits that pull into the wood/ply.
When using downcut bits for Acrylic/Polycarbonate I found it somewhat helpful (but not required) to add more weight Cutting acrylic panels for MP3DP - #52 by azab2c, but using the right bit for the task had more of an impact. Haven’t tried compression bits, they sound cool for certain situations. Am new to this stuff and learning…
