The classical PC experience
I can only recommend MS Office to anyone who needs an office suite for serious tasks. If you don't need perfect compatibility and the likes, there are good alternatives, even free ones. But if you are serious about your writing or your presentations, you need MS Office.
Pros
MS Office is the gold standard for its sector, and it's quite obvious since it has been around for so much time. I use MS Office for 20 years I guess, and I always liked it, but the jump was clearly around the 2007 version. It was a jump in quality that just put the suite so ahead of the competitors... it's true that today there are a lot of (free) alternatives, but it's just not the same, especially when it comes to compatibility. I use MS Office for work and the clients want a well-formatted document, not some cheap stuff you can do with free clients.
Cons
In my opinion, there is no problem, as it offers a software package that guarantees the development of any job in a professional manner.
