In my view (your experience may differ): almost always ignore a recruiter, unless getting out of your current job situation is so urgent that you're willing to waste a ton of time, or the recruiter presents a very specific proposal that makes clear that they've done their homework meaning that you are a great fit for a unique opportunity. In some cases going through a recruiter is a guarantee that you won't get a position, because a third-party recruiter tries to sell you to a company that has its own recruiters and is unwilling to pay the third-party recruiter's fee.
