What's a good replacement for Microsoft Office?

Trying Libre at the moment. Thought the “experienced” on this Site may have some advice.
Have been using Office & Outlook 2007 which I purchased but when I saw that Microsoft was upping the price of its disks to encourage yearly online licensing figured it was time to look elsewhere. eM Client’s solved half of my concerns.
If this is not the place to discuss this perhaps you could direct me to a Site?

I’m using Libre Office and am very happy with it. I used openoffice prior to that, but moved over to LO when development seemed to be more active on it. But now I see some updates have come out on openoffice as well.

Thanks for that Mike. Think I’ll stick with Libre Office. It seems to be fairly easy to adapt to. Regards.
