You're welcome to disagree, but after 10 years in the Nissan community, and multiple swapped cars, I'm not making this up.
As far as "which is harder", if you've been "hearing" something, then you need to question that source, and make them explain, in detail, why that's the case. If they can't, they're no help to you. There's a lot of "magazine tuners" out there who are just as lost as you are, but they love to give advice - it's usually wrong.
The forums here (240sx.org) have been around since 1997. There's a LOT of info. Good luck!
