Actually unpopular opinion: Mordekaiser is the cure for toplane.
When toplaners think of the best time to play they tend to think back to season 3 most of the time where toplane was an island shyvana renekton were the strongest picks and your job was to make it unpalitable to gank you.
In the current meta top lane is still an island. Its just an island that boyscouts go to for a camping trip. There is no longer nearly as many champions that can safely tell junglers to piss off because junglers are just so goddamned consistant. So even if you won champ select and have the enemy 20 cs down you can easily get ganked out of nowhere when you try to punish your opponent.
Mordekaiser literally removes this and kills you making toplane an even lane no matter what. He simultaneously makes it unpalitable for his ally to gank as he will be pushing most likely and his ult removes his allies from ganking as well. Id literally rather face a mordekaiser than play without mordekaiser in the game.
Tahm kench is constantly compared to mordekaiser but hes not the same. He doesnt remove junglers from toplane and his main problem is his q is way too big a skillshot for how much damage he does. Mordekaiser doesnt have basically guarenteed poke he just has a ton of all in ergo they arent the same.
