Salesforce-Not useful at all!

Bad

Salesforce is NOT a user application for sales! It is merely a data entry platform that uses a very primitive UI to access SQL databases through static reports. Lightning has been their 'new' UI for a decade & is still being 'rolled out'.
Task 'management' is literally just a list that doesn't do reminders and is wholly manual. Technically, you can label a task as a reminder, but it's only a label; it doesn't do anything.
All data is managed manually. Automating anything is difficult and time consuming. The standard SF response to setting up automations or connecting functions that the modern user would expect is, "of course it can do that! Oh, wait no, no, it cant do thaaat. But you can generate a report".
The most ridiculous advice from SF experts is to export to a spreadsheet. Why are we paying for a CRM that is only useful if the data managed in a spreadsheet?
