Sprite or SPB Backup for email backup...?

[parcou]

OK...I know PIM backup is free but I have never gotten it to restore my mail accounts successfully from one rom to another. They would show in TF mail tab but nothing was ever there when opening the account...OK could be me but no PIM...

=========
Which app would do the job of backing up all my 5-mail accounts and 1-exchange account from one custom rom to different custom rom???

I am hoping to have:
-all account mail-servers/settings/password/etc info carry over
-all email carry over
-hoping signatures as well????

All after the restore. So which one is king between the two???

PS. I will want to backup contacts as well to carry over. Thx
