Mate, they are very different kites. Look at this here, I took two screenshots from the website:
prnt.sc/n1jr04You should also notice that the GTS is a lot more sturdy than the section, which makes sense since the GTS apparently starts beeing nice when well into the top end of its range. You can jump any kite but if you are looking for something that is good in the waves and for jumping, you should try out the Nexus. Or just give the guys from actionsports a call all I know from the core line up is from watching them from the beach at cape town and talking to some good riders but I didn't talk to anyone riding a Section, only GTS, XR and Nexus.
