or is it better to get some other bachelor and than undertake flight training?
Definitely! The problem with all those aeronatical degrees in combination with a pilot's license is that the belong to the same industrial sector . In bad times when there are no jobs for pilots, there aren't any jobs for aerospace engineers (or aerospace accountants and suchlikes) either! (I know because I have both...)
Get a degree in a totally different field first (law, economics, medicine, languages, whatever) and become a pilot on top of that. You will never be unemployed.
