Should I major in accounting&Finance or Management Science?

I’m ending my sophomore year at college and I still don’t know what I want to major in though I’m sure its either of the two mentioned fields in the question title. Let me give you some background.

Currently I am an Accounting and Finance(ACF) major, I’ve taken most of the accounting requirements of my degree except for Taxation and in Finance I am only left with Applied corporate finance + 2 Finance Electives. Personally, Accounting disgusts me even though I manage to do Fine in it. Finance interests me and I see myself going over financial news many times a day, following the markets, but in class I mostly get my head in a fix with theory and I certainly need to put in a lot of extra effort to grasp the concepts afterwards. I did get an A into the Principles course but currently on the intermediate course even though I’m doing well in the quizzes, the learning curve is weird and requires a ton of extra effort on my part.
The degree on a whole is exclusive in my country with great job prospects in the corporate world: management positions in all fields in the corporate world, banking, Financial sector(provided CFA is given as a supplement, atleast level 1 by graduation) and every business job except for high value auditing or accounting jobs(require ACCA for that).

The other option is to major in Management Science(MS). I have only taken an intro level course to it because it was a requirement, the course itself had little value as we were taught the very basics like simulation, modelling,LP,regression etc in excel and why I enjoyed that much, it was very very basic and did not give much insight into the major. So I don’t know how I will find MS as a major.
MS is a new degree for my country but one that has a small but rapidly growing Job market locally, but plenty of opportunities abroad as well.. And Well OR is a field for the future as everyone says.

What I want?
I don’t want to pursue accounting at all beyond the next required course. I am unsure if Finance is for me because of how I struggle with it in class despite my interest(am I or do I just think I am?). I see my future in the corporate world in a how growth prospect position. It is important to mention I absolutely do intend to do masters a year or two after my undergraduate(from the best possible place, regardless of cost) in the field I eventually chose to narrow myself down to.
it is also pertinent to mention that the core Management Science major starts in the junior year so I will be starting it with everyone, but for my current major I’m 75% through with the core courses.

Possibilities on what to do:
1- Continue with my current major
2-Switch to Management Science.
3-Continue current major but take some courses on Management science that are open for everyone.
courses like: Decision Analysis, Optimization, Simulation Modelling. (Any good taking them with current major?

4-Switch to Management Science and take Finance courses that I would have taken if continued ACF major—all courses except Applied corporate finance which isn’t offered to MS majors—(MS with prowess over finance, useful??)
Finance courses like: Investments, portfolio management, financial modelling.

Here is a list of Management Science courses offered in the major:

Simulation Modelling and Analysis
Qualitative & Quantitative Methods in Business-
Decision Analysis
Optimization Methods for Management Science
Decision Behavior
Supply Chain and Logistics Management
Transportation and Logistics Management
Business Analytics
