Like Bulgy Snatch (LOL) said, the best way to find the marker for yourself is to try them. Some people think about all the factors when getting a marker. Like how easy it is to strip/clean if you get a break, how much air you use in a game, s'pose some people put what it looks like into it aswell, how much would it be to upgrade........List is endless!
There are loads of markers.......just try one!
As for Spyder, dunno. Only ever seen one used by some pro (can't remember who) on a TraumaHead Sportz dvd, but he had it ripping with the best of em!
