When ripping on a PC, the disk can be read as many times as necessary to get a parity match. If the disc surface has been abused, this could result in a more accurate file.
I've heard disks burned on the mastering converter, CD test pressings and the commercial release. All sound different. People on the other side of the planet noticed identical differences on home as opposed to reference quality equipment.
IMO, label paint is unscientifically applied and contributes to errors.
Some CDP benefit from a Discus or other damping atop the disc. Shock absorbtion is always a good idea for the player.
Computer burned discs may or may not match the ripped file depending on the quality of the writer. Almost assuredly, the burned disc will have a shorter life.
Ripped and burned discs sound 'different'. Better is in the ear of the beholder.
