one way link building with sites and pages with PR will give lots of benefits. Two way means reciprocal link building also helps you if you do healthy link building. But IMHO 3 way link exchange is risky. One expert told this. And i personally will not prefer to go with 3 way link building. In these all 3 link building process quality and relevancy should not be ignored. Keep it in mind.
