As far as I know the only difference between the types of Sikaflex is the slump.
This means the way it behaves until its gone off. There is low and high slump.
One type is for fixing above your head so as it wont fall down on you and the other is for fixing to a ground plane, which is not going to fall down. Have used Sikaflex for all sorts of applications in the past, some of which I was told couldn't be done. One of them was to tile a kitchen in an RV. I was told that the flexing of the walls would crack any adhesive so used Sikaflex as it doesn't go completely hard. There are many cheaper copies of Sikaflex but don't be tempted.

291
Resistant to weathering, seawater and ultra-violet radiation,
Sikaflex®-291 is the perfect all-rounder: an all-purpose flexible
marine sealant that bonds extremely well to all the standard
materials used in boat construction. Its outstanding elasticity
ensures a durable, long-lasting seal.

292
Bonding
Joints that are subject to extreme dynamic stresses require a
high-strength elastic adhesive with good gap-filling capabilities.
Sikaflex®-292, with its excellent shock-absorbing and
vibration-damping properties, has been specially developed to
meet these requirements in the punishing marine environment.
When your safety may depend on it, only the best is good
enough.

295
Bonding of plastic glazing panels
This is an application that calls for a UV-resistant adhesive with
a high degree of elasticity. Sikaflex®-295 UV combines the
necessary elasticity with exactly the right consistency to
maintain the required bond line thickness, thus ensuring that
thermal movements in plastic glazing panels are absorbed
progressively, without undue build-up of stresses.
Bonding and sealing of mineral glass

296
Direct glazing of mineral glass requires a purpose designed
adhesive with the right combination of application properties
and performance characteristics. Sikaflex®-296 is a fast curing
high performance elastic polyurethane that is suitable for all
types of mineral glass. It’s high UV resistance also makes it
suitable for backfilling and sealing operations.

298
Bedding and bonding of panels and sheet materials.
Sikaflex®-298 is a viscous, full-bodied adhesive that has been
specially formulated for the waterproof, flexible bonding of
timber strip decking, deck planking, plastic deck coverings and
prefabricated timber deck panels. It is easy to work with, and
gives professional results every time. The permanently elastic
adhesive layer has a cushioning effect absorbing shocks and
minimizing the transmission of impact sound.
