Yes. While many internal recruiters are not great they are typically a bit better than the average third party external recruiter. Most third party recruiter are entry level sales people who got the job right out of college and will never make a placement before moving into another career.

There are very few high quality third party recruiters but the ones who are typically are very good but overworked and only serve a specific market. If you are not that market then you are a waste of time to them.
