Similar to helmet choice, it really comes down to what you want to do with it, where you’ll wear it, and what’s your budget. Leather is still regarded as offering the best protection from abrasion in widely available product. Sure, leather is more of an investment but it should last a long time if it is taken care of (clean it, and condition it). Textiles can generally be found cheaper, they are lighter weight, and offer more breathable options. They can also be more technical in their uses as is found in touring jackets with multiple layers.
