I'm a believer in market efficiency. I don't believe anyone can achieve better-than-market returns over the long run without some kind of private advantage, like insider information. That's 99.9% of us. The only thing I can control are my costs, which I should drive to a close to zero as possible. My personal portfolio is entirely low-cost, no-load index funds and ETFs. I've been very happy with that decision.
Passive funds are the best for most people. Not 99.9% though. Market efficiency is not a static thing, and strong form is simply not true. For large cap stocks, fairly true, but not always. For small caps? Much less so. For people who think technical patterns are their savior? Absolutely, they are losing out by not going to passive funds. But there is a reason Warren Buffet did so well in his early career (and it wasn't because he had a ton of extra information). Now, well Warren makes money just by talking about a stock, but it wasn't always that way.
As more and more people move towards passive funds, the more and more control large activist investors will have in a stock. For example, if literally everyone was in a passive fund, no volume would be traded and stocks would stagnate. It's a sliding scale until that point.
I did pretty well investing in smaller companies in industries I really know, above and beyond the fees I charged (albeit only for 4 years). That being said, I am now heavily restricted from what I can invest in, so I stick to all passive and like most others, do just fine. I don't see us tipping the scales too far in the passive direction anytime soon.
To the OP: Just use passive funds, and don't pay an advisor to do so. All of this is independent of tax considerations, which can affect things.
