Can an electric griddle sear meat and smash burgers well?

This is where consensus splits. High-trust community discussion (r/grilling) notes that many flat indoor electric griddles cook pancakes, eggs and fried rice well but underperform on smash burgers and searing because they can't recover heat as aggressively as a dedicated outdoor griddle. Hybrid grill/griddle units add ridged grill plates but draw mixed reviews on actual searing.
