Hpf pays via Paypal, which, in my opinion, is by far the safest, quickest, and simply best method. I don't know if it's a scam or not, but I've seen a few pictures that have proof, so I have no reason to not believe it (especially since they're partners with Yahoo).
As for the actual SEARCHING quality, I have found it to be very high. I immediately tried searching for a website that I'd been searching for for two weeks on Google, and I found it as the first result using the same keywords. I'm pretty sure that the search engine is the same as Yahoo, and would therefor get the same results, although it may even be improved.
If you're wondering why they're able to do this, it's because of both the ads when you search things, and also because people that are getting paid to search tend to search more, therefor increasing Yahoo (and HPF's) traffic. Just so you know, you can't just type in a bunch of random things and then go on to the next word. You have to click at least ONE of the results - I should know, as I made that mistake myself, thinking it was a bunch of easy money
You are paid 45 days after the first of a month, so it isn't exactly quick. It isn't really a 'get rich quick' scheme, though, so you probably need the time to get it. Whether you want to use it for power, or casual surfing, I believe this to be a good alternative to simply using plain Google or Yahoo.
