I can't say whether or not you recall correctly about Javad's plugs.
But in any case, what might might have been the belief of someone
"at one point" might not be true in the long run. And finally, what
does "better" mean and how was it determined?

So do I, Brandon, so do I. But after hearing--over the course of 7
years--nothing but good experiences with the F5DPOR and many, many
poor experiences with alternatives, using the F5DPOR is the best
advice I can give. Also, note that I said "alternatives are _likely_
to disappoint", not that they will necessarily be inferior. YMMV.
BTW, whenever I see prices on these plugs, they run about $11/ea. Now
I don't know about other 20V engines, but mine uses only 5 plugs
(every 75-100K miles) and that makes the cost differential (i.e.,
cheaper plugs) a pretty insignificant issue, IMHO. It's always nice
to find something with better performance, so if you can get more
info from Javad about _how_ the F6DTC performs "better", it would be
