Pls recommend my first fragrance for college

I'm new in fragrances, this will be my first fragrance and i just want a fragrance that lasts all day in college, smell premium and good, my budget is 10-12k for 100 mi

I tried Sephora or decants but everything smells the same to me like i can't differentiate that much like notes, dry down and opening etc, so pls tell me wht fragrance you got most compliments and performance with.
