It depends on your career goals, go to the commercial bank, it's stable, you will have a great work-life balance and medical/loan benefits, the working environment might be not such pushy, but the job might be "boring" as they have a standard system to do all the things, and you are the person who can be replaced by anyone. Therefore, working in an investment role will be more fun and you need to keep learning all the time, every deal is different, sometimes you will have to spend your spare time working/researching the projects, but the career might be better if you deliver a great performance. 

Both of them have good reputation, NF group is quite famous too, so don't worry about the company name, after you have work exp, your next employer will pay more attention to your previous job nature/ job duties you have done, rather than the name
