As some have mentioned tanky junglers (malphite being the best example) have become more popular and their innate cc is all they need for ganks, escaping and dont need the damage, armor or unique procs offered by lantern. Philo stone, boots of speed and heart of gold in that order is the perfect early build for such junglers.
Also mentioned were the tank junglers colleagues; the hybrid, aoe damage dealing junglers (udyr and shyvana the best examples of this) who are also seen more often than say traditional lantern users (shaco). Aside from these types of jungler, I still think lantern is a great item.
Bruisers in solo top are different, I build wriggles then mercs on almost all of my solo top champs. Provides cheap, early: armor, mr, ward, sustain, farm assist.
