With BusyContacts I can see my contacts from various sources all in one place. This is a great tool to manage contacts in various places like Gmail, iCloud and local, all with one tool! I have connected my Gmail account that is use for my business and my Gmail personal account as well as my iCloud personal account and can see contacts from all of them in one place. It is fairly easy to copy and paste between them. You can easily duplicate a card and then edit it which I do when adding a new person to a company so I don't have to retype everything in. That is somthing you can't do with the standard Contacts app. Review collected by and hosted on G2.com.
When you have multiple accounts, it can sometimes be hard to combine information to consolidate across accounts. You may have to do multiple merges and combine contacts to achieve your desired results, but it's still way better than trying to do it all manually with cut and paste.
