She's not in the best spot at the moment after her nerfs, the nerfs to the Perseverance mastery, Spirit Visage and Sunfire Cape, and the meta shift to ranged top laners. She's probably still viable, but not as strong as she once was.
I prefer durable top laners with high scaling, so I would recommend trying Irelia, Nasus, and Mundo. This advice also applies to Trundle. They scale very well in duels and teamfights, Irelia is very strong against ranged opponents and also capable of dueling bruisers, and are very difficult to push out of lane with a Doran's Shield and Health Regen quints augmenting their natural sustain.
Though, judging by your current top laners you seem to prefer lane bullies. If that's the case, I would suggest Gnar, Yorick, and Kayle.
