I'm a student so I kinda need full compatibility with Microsoft Office Documents for school. I was wondering if Office will run without major problems in Crossover, Wine, or playonlinux?
The answer is yes. In fact the other two are also based on Wine.
Considering just Wine, see this question. But later versions of MSOffice, 2007 and 2010, are much easier to install in Wine than older versions like 2003 and XP. For 2007 and later see my other answer. (Personally, I was not able to install msoffice xp or 2003 in Wine, although I deem it possible.).
Playonlinux has the advantage of offering the possibility of using different versions of Wine for different programs or program versions. See this answer for more details on installing msoffice 2007.
CrossOver greatly facilitates the installation of MSOffice, even of different versions that could be used in parallel, new and old. (I was able to install very easily msofficexp.) This is a very useful and recommendable application, especially for the users who want the comfort and are ready to pay for it.
(To make things even smoother, you can improve appearance of the programs installed in this way; for Wine and playonlinux, look here; for crossover, here.)
