Which is more polite, ではまた or じゃまた?

deha/wamata and others, jya/jaomata. Which one is more polite?




When expressions are shortened, they are usually considered less formal and
thus sound less polite. This applies to `では vs. じゃ`: じゃ is less formal and
thus sounds less polite (but can sound more friendly). Other common examples
include: `しては vs. しちゃ`, `している vs. してる`, `しておく vs. しとく`, `してしまう vs. しちゃう`, `すれば
vs. すりゃ`, `しなければ vs. しなきゃ`.
