@Piersl I use conflict palettes for specific groups of actions - e.g. to process Markdown, so definitely consider it as additive to those.

Alfred I use for launching many things so it is muscle memory to trigger things from that, and I get the consistency of a single trigger point.

Conductor allows me not just to run KM macros, but other things too (edit, toggle, delay, etc.). Even if you didn't use it for launching, you may find other features useful to have around and accessible via Alfred.
