It would be a closer comparison if you compared longlining to planers. Planers really can fish as far from the boat as you would like where longlining you are limited to length of pole. Spiderrigging is more towards catching located fish holding on structure of some sort and keeping a bait in their face. I cover 36' of water in 2'-3' separations while longlining, dont think when fishing is good and a lot of traffic on the water I would want to cover a wider path. But that is my opinion and it is worth exactly what it cost ya, and bear in mind I have never ran planers for Crappie. And there is a video some where on her of Charlie Brewer Jr running planers that someone I am sure could find. Might even have been a homepage article.
