gecko's kit is very robust, but inefficient. i really don't see teams picking him for anything except his wingman (dude can basically be used for entire execs lmao)
hes a plant /defuse allower like harbour and sage and other smoke agents, pretty clutch element as well + info gatherer i think he will get played alot
people will try him because he's new and then after like 2 weeks his useage will drop, but he will definitely still be played. He looks like a fairly balanced agent to me although its hard to say having seen half a map
