Could you say what's good about it for you? Like task-management software, I think the "money management" category hides a lot of variation in how people think about and do things. The right product for one person is definitely the wrong product for another.
I switched because Personal Capital has much nicer UI and tools for understanding your investments. As my income increased over my career I found that budgeting was becoming the least complex part of my financial life compared to managing retirement, brokerage, stock grants, etc. funds.
I agree on PC being much better in tracking investments and performance especially as net worth increases compared to mint. I have also found it to be more solid connection wise vs. Mint over the last year where mint has really gone downhill for me for some reasonwith many unresolved issues, whereas the PC support tickets I filed were resolved rather promptly. Not all is great, categorization and tagging of transaction is terrible, and you can't have sub categories, so if you need that, you need to use something else, which is not great.
