Which type of phoenix clone is best?

[ilych]

I'm looking to get into rebuildable atomizers for dripping, and these clones look like a great product. I have done a lot of research on building coils, and I think I'm ready to give it a shot.
I'm looking at the clones on fasttech, and there are a bunch of different phoenix products.
Are there any major differences?
Which one is the best?
there are nimbus 2, v13, v12, v10, v9, v6, v5 (with varying amounts of airholes), v4, and v3
edit: Alternativly, if the phoenix sucks are there any other cheap options?

I have a v9, and it sucks. Even with some drilling, it is not good.

i have the v5 with 1 airhole and its pretty solid. If u like airy draw ur goign to have to drill that airhole out, the stock one is tinnyyyyy
