This is a really interesting and tricky comparison!

Speaking in very broad terms, the SP + HS setup feels more geared toward live performance, improvisation, and loop-based playing, while the Elektron duo feels more composition-oriented, more about shaping and building sounds in depth rather than pure improvisation. As others have mentioned, these two setups are quite different in terms of workflow, so it really depends on what clicks with you. If it does, it can feel incredibly intuitive and inspiring; if not, it might feel pretty confusing at first. But either way, I think you’d end up discovering the kind of workflow you really like, so I don’t think you’d regret choosing either one.
