I really like using
. He's easy to use, and has great sustain. I usually build
then
or
and then start stacking defensive items. Unless I'm not getting shit done, or the other team has a fed carry, then I'll grab an armor or mr item first after jungle item.
Just up W>Q>E, max E then Q. Tanky, good CC, great early/mid game damage (and very helpful late with Ult/Knock up/Dive). Works pretty well in the low leagues (Silver)!
Works well if you play him right. He can split push very well and escape out of most anything. I haven't seen a too many players use him to carry actually engagements though (no in the lower leagues). I assume he just takes more skill to play.
Can be a nightmare in solo queue, his silence is very strong and a well timed ult will outright win a team fight. Great sustain through life steal in the jungle as well. Not sure on his clear time as I don't play him much.
Tanky as hell, and his passive is very strong in the early game. If he get's fed he can do quite a bit in Silver league. I feel like he relies quite a bit on his team mates though, so I haven't used him much in solo queue. I have seen him played as a support here and there, not a great choice in my opinion but that may just be the players I've seen use him.
In Silver this guy either does nothing or rapes everything. Assuming you play him right he is a fairly tanky fighter with very high damage potential from what I've seen. He has a great slow and can stealth (something that is a terror in low leagues), popping out with high burst. He looks like he would be pretty easy to gank with and secure kills.
Oh, almost forgot, if you're just looking to kill a bunch of people
is a good pick. He is very fun to play with a resetting leap and extremely high damage. A bit harder to jungle with though as his sustain isn't as good unless you max "W" first. Also in team fights it takes some practice to not just die instantly since he is so squishy. A while back he had an evolved "R" that reduced damage by like 40% and I went 36-5 with him, but now he is harder to play :(. Pretty easy to gank with though, and in team fights even if you die you can usually snipe their most fed carry first. I try to just make it a goal to kill the 2 squishy carries before I die :P
Overall the main thing I would point out is that you can pick most any viable jungler and make him work from early to late game so long as you play him right. I don't think at our skill level it really matters who you pick (counters, current meta strength, etc) so long as you can play the champion well. I've shit on people that hard countered me in lane, and been shit on by people I counter. I've carried the late game with champions that have a weaker late game as well, all that matters is how well I do from start to finish.
Unless the champion is ridiculously strong like Kha'Zix pre ult nerf (but even then it doesn't matter if you don't know how to use him), I really don't think it matters who you play. Pick someone you enjoy and learn to play them well.
