AFTERPAD

I know the nimbus is better, I'm just wondering how much better. I really want a controller but I can't find the nimbus anywhere in Europe (I'm living in Romania and there's no Apple Store here). There are some Hong Kong sellers on eBay that are selling it for 75$, and I would also have to pay up to 20$ for customs taxes (vat). Paying ~90$ for it is not an option for me.
The stratus xl on the other hand is available on Amazon in many Europe countries and I can get it for around 60-70€ with shipping taxes, which is...ok. I know it's more then it's worth it, but I could pay that.
So I'm really leaning towards the stratus xl so far, but it bugs me that it doesn't have a built in battery, no Bluetooth 4.1, and the fact that the triggers are so sensitive from what I read on the review. Almost everywhere I look the nimbus is cheaper then the stratus (idk why), but I don't know how long I'll have to wait for it to become available here.
Thoughts?

LE: forgot to mention, will be using it on an iPad Air 2.
