What Goodbudget does well

Straight from their own help pages and announcements.

Built on the envelope method: you set money aside for each category before you spend it.
A Free Forever plan with 10 regular and 10 more envelopes, 1 account and 2 devices.
One budget syncs across your phones and the web, so you and a partner see each spend.
Debt tracking on both plans, with Debt Accounts on the web to follow payoff progress.
Scheduled transactions on web, iPhone and Android, with an optional reminder email days before.
Premium imports pending transactions and learns which envelope each store usually goes in.
Manual import of QFX, OFX and CSV bank files.

Automatic bank sync is Premium-only, works with US banks only, and doesn’t cover investment, crypto or loan accounts.

The short version
