Living near Macau and East Timor (as well as relatively near the former portuguese territories in India, where Portuguese is also spoken), I would say Portuguese would be a good option. But the choise relays heavily on what you intend to do with it : just for personnal development, or do you also plan to make a professional tool out of it?... If you're planning making your living through this new language, notice Angola is potentially one of the most rich countries in the world, having petroil, diamants, gold and other natural resources; and all big trade there goes on in Portuguese.
Anyway, don't give to much credit to that Brazillian x European Portuguese talk. It's the same language, grammatically speaking, with a minor differences in elements placements, elipses and few more (I'm talking about educated urban standards, of course, not regionalisms or sociolects); only the phonology is quite different.
About phonology, many people prefer the softer sounding Brazillian version. That's a matter of subjectivity. Yet one objective factor you should have in mind is that European version is phonologicaly richer, meaning, it has more variety of sounds (which provides more expressive potential to the language). in fact European Portuguese phonology is one of the more complex and rich in the world. In contrast, Brazillian version of Portuguese is relatively poor.
