IANAL. If you adjust status in the US you can also apply for AP/EAD if your original visa/legal status expires. You can't do that if you opt for consular processing.

Nothing new there, but under the new rules the former is no longer an option and you'd need to leave immediately. On the plus side consular processing tends to be cheaper and often faster (AOS and all the approvals vs the consular processing fee and a plane ticket).
