i think currently Killua and Gon are probably strong enough to go toe to toe with some Phantom Trope members

even back half way through the chimera ant arc Melereon said that Killua was Squadron Leader level which means he's around as strong as Zazan who gave Feitan a good fight before he well...cooked her to death

in the recent arc didn't Hisoka and Tsubone imply that Killua was around Illumi/Hisoka level? Gon's probably not too far behind considering they've had the same experience and training
