which one is better？ 
Assume the 
mainly builds AP&AS. Not the who builds full AD or some AD. Not the who simply builds AP&MagicPenetration and counts everything on mushroom.
Gold efficiency & build path ignored.
Thanks.
Edit: Thanks everyone for posting. Here is what I would like to build on my jungle teemo now.
I build Nashor's first, then go into either Liandry's because the mushroom's do immense damage with Liandry's OR if I'm thinking of 1v1 / split pushing, I build a Void Staff + Lich Bane + Runaan's. The speed and burst per dart is quite intense.
Hopefully, that helps somewhat. Laundry's for mushrooms but if you want more upfront burst, Void Staff seems to work the best. Lich Bane comes easily once you start kiting people down with Nashor's + Void Staff.
An early can hurt a lot, so imo, I recommend this one first.
Alot of Teemo's damage is DoT, so why not compliment that with even more with Liandry's?
DFG then lichbane. gg
personaly i like this for my teemo builds each new line will be your next back

this can be bought whenever but i really try to delay it i mean yea it makes your shrooms hurt like a bitch but if thats what your relying on for damage thats okay then i guess prolly would be better
I do : in order.
But you can always replace the with a .
Honestly, your DOT damage on poison (E), your Q and your shrooms are all AP scaling. Late game build with nashdors, your autos will hurt a lot. Not as much as AD teemo, but then again, you'll never have the chance to deal enough damage before getting one shot by the enemy team. I think it's wise to follow this build, but then again, it's up to you. I'd rather go burst than constant dmg on teemo.
I tend to think Liandry's into Nashor's works very well. I often close it out with Void Staff, Rabadon's Deathcap and Runaan's Hurricane, but I could consider Lich Bane over Rabadon's. Whatever floats your boat.
