Please define “better.”
If you are looking for software that can import transaction level data from Quicken, I do not know of anything out there.
If you have a paid subscription to Morningstar, you can export your portfolio holdings from Quicken and analyze it there, or with their new Investor features you can link directly to many brokerage accounts and import your holdings, similar to Quicken's Simple investing mode.
Exporting/import in QIF format would be about the only possible format that this might be done in.
