django-modeltranslation

Uses one field for each language/field combination, so having 3 languages and 3 translatable fields will result in 9 extra fields on each database table. It rewrites queries in order to return the current language, but the contents of the original field are undetermined if a field is translated.

django-nece

Also uses a jsonb PostgreSQL field, but has a bunch of custom QuerySet and Model methods to get translated values. It also requires one to inherit from a TranslationModel.

django-i18nfield

Stores JSON in a TextField, so does not allow lookup, searching or ordering by the translated fields.
