Troll and Ursa are the type of heroes that you cannot really trade with... There are some others as well, like Slark for example. These guys either keep you from getting away or just have escalating damage throughout the game. But they usually have other issues that make them less desirable to play... Troll has that ulti that takes away your control. Ursa can be kited, Slark has quite shitty stat gain and can be quite bad if you dont get off to a good start... In a 1vs1 these are some of the nastiest heroes, but this game is not 1vs1.
Ursa is the best 1v1 in 5v5 game. It can tear sup apart only 6 to 12 hit within 3 sec. But need BKB !!!!! 
Yeah, Troll is most definitely the strongest 1v1 hero. Of course, there are counters to him, but in most situations against single carries (not ck, naga or pl), he will be victorious with his permastun.
