A personal representative deed and warranty deed are the same only in that they both convey ownership of land. The types of title assurance that the different deeds provide to the new owner are very different.
Conveyance
A conveyance of land is the legal term used to describe when one person acquires another person's ownership of the land. All conveyances must be evidenced by a written deed to be valid.
Warranties
When a deed is signed, it creates warranties from the old owner---the grantor---to the new owner---the grantee---regarding the condition of title to the property. The type of warranties made in the deed will depend on the language used in the deed.
Warranty Deed
A warranty deed provides the grantee with the highest assurances from the grantor regarding the condition of title to the property. By using a warranty deed, the grantor assures the grantee that there are no defects in title at all and the grantor is obligated to pay the grantee for any damages the grantee incurs due to a problem with title to the property.

Personal Representative Deed
Personal representative deeds are reserved for use in connection with probate---after the death of a property owner. The personal representative appointed by the probate court will use this special type of deed to convey the property to the heirs of the estate or sell the property to a third party, depending upon the terms of the will.
Special Warranties
The warranties provided with a personal representative deed are very limited. The warranty simply assures the grantee that the personal representative did nothing to cause a defect in the title during probate. Once the estate is closed and the personal representative discharged, the warranty is of no practical effect.
