Ive had a lot of success with CT1 when other adhesives have failed.
However, different adhesives have different properties that mean they are better at different jobs.
Most of the "best" no more nails type adhesives are MS polymer based. That's Modfied Silyl polyethers, but not all.
As to why? Quite complex material science, meaning different adhesives bond to different substrates in different ways, and have different finished properties when dry
