Why Insteon over X10?

X10, Insteon, UPP, and ZigBee can all perform similar lighting control tasks. Irblaster.info prefers insteon for several reasons outlined in the insteon product comparison application note. In summary, here is what the note has to say:

INSTEON: Moderately priced, highly reliable Dual-mesh RF & Powerline technology
UPB: Expensive single-band technology
X10: Inexpensive but lacks the robustness, flexibility and reliability required by home-control applications
ZigBee & Z-Wave: Single-band (RF-only) wireless networks that require a network controller
