Curious question here, something that's been on my mind for awhile, when you're playing as jungler which lane do you find toughest to land a successful gank on?

Mid is generally considered the toughest lane to gank. Top is generally considered the easiest to gank. What lane you gank shouldn't matter if you position well.

mid or bot depending mostly on how much cc they have, top lane is a cakewalk

mid for it being such a short lane, and bot for it being warded 99% of the time.

On blue I get around to top the least, because I rarely wander over there to do wolves, only going to give my mid blue or to counterjungle their red. I make a point to gank top every time I give blue though, because it turns into kills more often.

On purple top is the easiest for me, and bot is the hardest, and I rarely, if ever, go down there unless it's a very close lane, because if they're winning by a lot they dont need me, and if they're losing by a lot it won't turn into anything unless I'm very fed/farmed.

I gank mid a lot just because it's easy to get to on my way to the other side of the jungle, and if the jungler shows up a lot in lane, it makes the enemy scurrd, or whine for more ganks.

Mid is short so thats hard to gank. Top can be hard just cause most solo top lanes are sturdy champs who are equipped to deal with ganks. Bot is also often warded so that can be difficult. But usually I find bot is easiest to gank. Bot lanes offer more CC to help you gank and are usually squishier champs (in general)
