Debian is usually very stable, which means drivers and kernel versions will be outdated in comparison with other distros, which can make you lose possible performance. To be fair I wouldn't worry too much about this though since I don't expect the performance to be significantly different, but it's something to take into consideration.
Don't be afraid of trying a different distro, RedHat or Arch based for example, just make / and /home different partitions and you should be able to install over your root without affecting your home so it makes it easier to switch system if you want to.
