Short answer: alcohol is worse to choose.

Why:

• Alcohol (madya) is strictly forbidden in Jainism because it clouds the mind, weakens self-control, and leads to hurtful actions and karmic bondage. It harms the practice of ahimsa and samyak (right conduct). Both Digambar and Śvetāmbara traditions forbid intoxicants, including alcohol. So, from a Jain dharma perspective, alcohol is a direct obstacle to spiritual progress. If you want a concise justification, see the general guidance against alcohol in Jainism. ( jainknowledge.com)
• Eggs are also avoided in Jainism because they contain life or the potential for life, and consuming them involves violence toward living beings. While many Jains avoid eggs, the emphasis is typically framed as non-violence toward all life. This is a strong guideline, but the ethical weight of alcohol as an intoxicant is usually considered higher due to its impact on mind, conduct, and vows. For the egg question, see the explanations on why Jains do not eat eggs. ( jainknowledge.com)

Brief takeaway:

• Alcohol: strictly prohibited and considered particularly harmful to spiritual discipline.
• Eggs: avoided as part of non-violence toward life; still a serious restriction, but the direct spiritual hazard of intoxication makes alcohol the more “worse” option if you must choose.
