Generally speaking, these are rare events in both sports but one allows much more time for rescues.
You're on the surface, generally with a life vest, don't have to worry about running out of air, generally the guides inter-communicate and take you to hot spots of fishes or turtles or whatever... tropical warm water. Biggest difference is access to air rather than having to be "self-sufficient".
The bolting techniques used in caves are fucking terrifying. They work, but they are terrifying.
And also using temporary bolts as the Coeur 8 mm, which is rated for 2 kN before deformation in the worst direction (and the mechanism of those bolts are more akin to a cam, making them squiggle a lot in the hole, which is safe, but scary. My ice axe don't squiggle).
Obviously you use redundant bolts, and there are much lower forces in SRT than in dynamic falls, but I still think it's scary as hell.
