LibreOffice is an awesome piece of kit! On setup, they let you select the "tabbed" UI if you prefer something closer to MS office.
Collabora Office is another one that seems neat, have not used it before though. OnlyOffice has weird Russian ties and GPL incompatible licensing shenanigans, I would avoid them for the most part. WPS Office has the best compatibility with MS Office files on Linux I think, but it's closed-source so not great either. There's always running a VM / dual booting if you must use MS Office.
Honestly, MS office files have worked fine on LibreOffice, the only big issue I've found is that translucent images are a little broken when going from Impress to PowerPoint (all images share the same opacity for some reason?)
