Here’s my list from most to least bothersome.
- holo scratches
- numerous holo print lines
- edgewear
- corner wear
- weld lines
- front centering
- silvering
- a single holo print line
- back centering
Print lines are definitely bothersome to me if they occur in number (i.e., Neo Genesis with 5-20 print lines per card), but a single print line does not bug me at all.
There’s also a distinction between print lines on the surface of the holo (e.g., WoTC era) and print lines that occur due to the joining of the foil sheets (e.g., “weld lines” from the EX era). Weld lines do not bug me as much as numerous print lines.
