Which math is easier in IB?

I'm curious to know, which math subject do you find easier in the International Baccalaureate (IB) program? Is it the more conceptual and theoretical approach of Mathematics HL, or the more practical and application-focused Mathematics SL? Are there any specific topics or units within each course that you find particularly challenging or straightforward? Additionally, how do the assessment methods and grading systems differ between the two, and how do they impact your perception of which one is easier?
