Urgot- Why him?
Urgot is an INSANELY strong laner. You cannot beat him from level 1-6 and then it's not getting better. Team fights aren't that good but because of your passive they still are really easy and winnable. Also your R fears champions so it's easy to win lane as well with fights. The only big con about him is that he can't really win vs ranged champions. I will say everything below. What will you know after the guide:

Matchups
You can check them on any kind of counters site BUT Urgot is the worst vs ranged or/and REALLY mobile champions. The only champion you can fight which is MOBILE and Ranged is kennen which has a 44% winrate vs Urgot. Overall good experience vs meele and bad vs ranged and/or mobile champions.
Laning phase
In laning phase you plan to trade from levels 1-3 and then you play more passively until a big powerspike (such like level 6 or item). Over all the laning phase isn't that hard but can be significantly worse vs certain matchups like VAYNE.
S14 14.4 Urgot
Urgot is a strong champion with few cons and a lot of pros. I recommend to pick him vs meele matchups since he wins most of them. To the point he is really strong right now and I would put him in S tier since he is not that hard to pick up and easy to master.
In my opinion you should try out Urgot because what do you loose if he isn't the right champion for you?
