What do you like best?
It does what it says, within the limits of the Quicken product set.
What do you dislike?
Primarily, it's that the product can't totally solve my problem because the Quicken feature set doesn't support it. I wanted to load historical 401(k) data, for a long-running account, to Quicken Mac. Not possible without using Quicken Windows; and then it required converting file formats; and a supporting bank. I had 10 years' CSV data downloaded from T. Rowe Price; had to convert to QIF for import to Quicken Windows; then try to export for Mac use. Finally failed importing to Mac.
Recommendations to others considering the product
Carefully research what you need to do before the trial. A lot of Quicken scenarios simply aren't supported at time of data import.
What business problems are you solving with the product? What benefits have you realized?
Personal finance. I didn't resolve my goals. I bought the product but no longer use it.
