I use both the Effetto Mariposa tape and regular glue. The tape is much easier and faster, but it weighs slightly more, and has more thickness, making the tire sit higher on the rim. The Effetto Mariposa is supposedly good enough for cx, it's likely overkill for road use.
Removing taped tires is much faster than glued
I have taped a flat tire roadside, but I think taping would be at least as good as slapping on a preglued tub. Not many flats using Effetto Mariposa latex sealant, until the tire gets worn thin.
