IMO these days I recommend people just download OnlyOffice if they want something offline. In my experience it's never had an issue opening an office doc and the UI is much better than LibreOffice.

Personally, I find the perpetual licenses less appealing because they are costly, particularly when used on multiple devices. For instance, with a perpetual license, you're typically limited to installing it on just a desktop and a laptop. In contrast, subscriptions offer greater flexibility in this respect, accommodating usage across several devices.
