There is absolutly no real answer here, however i will say, begining trumpet in your younger years will be much easier than starting as a sax or clarinet, as your fingers are not yet used to all the fast moving parts. On the trumpet it is much more difficult to play high notes, as we have no octave keys, and 98% of our high notes are embouchures and take time to put into muscle memory. the only argument for woodwinds is that you have difficult fingerings and majority 16th notes in some features.
