DB,
I noticed your same question at a different thread on WMRIX earlier. I believe those who are interested in income/dividend stream are very much interested in ADVDX like high dividend funds. You may get valuable response/comments/feedback had you posted your question at different forum such as "Investing during retirement" and/or "Income and dividend investing" IMO.
Another approach is to search topics on PRPFX and ADVDX, insert these names separately into a box usually apprear at top right of the forum page, and you will get a tons of opinions.
If you run the M* X-ray (though some people may say the result won't be accurate) on ADVDX and PRPFX separately, you will see big difference on their holdings. ADVDX is more like a global stock funds with strong interests in dividend while PRPFX invest heavily in US Treasuries, gold, etc. Fundsnapshot at Smartmoney.com allows one to compare funds returns up to last 10 years, if you are interested in the past returns.
I believe, each will fit into one's port depending on the objective. For example, I am not interested in any yield/dividend so I would take PRPFX over ADVDX. JMO. KM
