I'm not positive which regeneration you're talking about. I'm assuming their base hp regen? Because if you're referring to the jungle item that's only against jungle camps.

Now is the bonus damage proc a singlular effect or is it continuous for the duration? If it's singularm sure smite out damages it big time, but if it's continuous for 6 seconds You could easily out damage ignite with it.

I'm going to throw the math down here just assuming that it's continuous.

We'll say level 11 just for fun.

Ignite: 50+20*11= 270: 270/5 = 54dps

Challenging Smite: 15=3*11=48: 48*5(WW ult)= 240

So numerically just from that ignite comes out ahead, but if you factor in the fact that ignite is over 5 seconds and the challenge smite mark lasts for 6 seconds. WW ult is ~2 seconds long, so you still have 4 seconds to hit more if they're not dead already. One more basic attack and you out damage ignite. Now there's two other effects to factor in, obviously ignite chops enemy sustain in half, while challenging smite chops the damage they do to you by 20%. I'd honestly say that challenging smite on a top lane WW would be perfectly viable. Not to mention that it's better for a sudden burst, where as Ignite is a DoT. They both have their benefits, but I'd say that if you're looking at flat damage, challenging smite is the better option.

Now what we're not looking at is the fact that in taking a jungling item in the top lane, you're not getting really any useful stats until you get it's enchantment, so you'd be looking to eventually pick it up rather than start with it otherwise you'd be largely useless for a good chunk of the game.
