In my opinion, wordpress is ok if you want to have a personal website. Xenforo or other forums platforms gives you more possibilities.
So you have to know what you will do if
Only alone or you prefer some help.
The differences between a blogging and a forum platform are:
If you start with blog, you can grow faster than if you start with a fórum. Meanwhile if you have patience or a couple of friends to help you grow up clever and the success will be burger..., I recommend you a fórum platform. And by the way; my favourite is xenforo as paid and phpBB as free.
