If it's your first bass and you are years away from playing for money, buy whatever you like.
As mentioned before, you will play it more if it's attractive to you.
If you're already famous or a prodigy/virtuoso, shape means nothing because you'll be accepted as a great player.
For everyone in the middle, a more conservative instrument makes sense depending on where you live and what others on the same scene are playing.
If everyone in your city playing the same venues as your band has pointy guitars, a P-bass might be considered odd.
