ehh, it depends a lot on the individual; there’s a lot more scope for interpretation in Islam depending on both religious and cultural variations.

Islamic slaughter follows the same basic method - must die from blood loss, etc - but the prayers said over the animal while this happens are different, and some people consider this significant. Also some people consider certain kinds of shellfish haram, while others consider anything that lives in the water to be completely exempt, etc.

Halal has vastly simpler and more livable-with rules than kosher, and while (apart from alcohol) kosher food is a subset of things that can be halal, it’s not always the case that they’re a subset of things that are halal.
