Hi,
When I began to pick the disc padlocks, I began by the chinese disc padlocks. I picked a lot.
I would advise you to begin to pick by chinese disc padlocks. It will be more easy for you in the first time, beaucause the chinese disc padlocks haven't false gates, just have right gates. But, something is very, very, very funny

, when you will be able to pick the disc padlocks Abus, it will be lot easier for you to pick disc padlocks Abus than to pick chinese disc padlocks.
Why ?
Beaucause the chinese disc padlocks have a bad mecanic, and more you will pick a chinese disc padlock, more its mecanic will become bad.
The same disc lock with a bad mecanic, you can open in few seconds, or more ten minutes.
It's incroyable and very frustrating.
So, when you will be able to pick the disc padlocks Abus, you will want to pick just the Abus, beaucause you more will enjoy picking disc padlocks Abus than chinese disc padlocks.
But, it would be a mistake to do not more pick chinese disc padlocks.Here my study on different brands chinese disc padlocks. Here the first chinese disc padlock, that I picked and the tool (detainer) that I used for pick all my chinese disc padlocks

Conclusion :Point of view picking difficulty , it's the same.
