2010sp5 v 2011sp3

I am off contract at  the moment, because I am only a part time design business I dont have the funds to upgrade each year,

I have been using 2010sp5, but am entitled to install 2011sp3, does anyone know of any major bugs with 2011sp3, would I be safe to install and use this or should I stick with 2010sp5

Thanks,

Brendon..
