It's still better than anything else and the de-facto standard so you need it.

Clients will send you their PowerPoint template and want you to use it. They will send you their complex spreadsheets riddled with VBA macros and you will need to fix them. They will invite you to a Teams site because that's where their project updates go. I just don't see how you can avoid it as a consulting company!

For things like Excel - We can say it's 'bad' but I've not seen anything do the job it does better. And besides, even if it was bad, it doesn't matter - as a consultant you need to use it because your clients probably want your workings as part of the deliverables, and if it's on Google Sheets they often won't want that.
