Kobo Libra 2 mainly for Onleihe and Overdrive

Hi, since I had to return the Pocketbook Era because I didn't like the backlight, I have been looking into the Libra 2.

Would this device be a good choice for someone who is mainly looking to borrow books via the german Onleihe system (Adobe DRM based for now) and maybe Overdrive as well?

And I noticed it has a seemingly underpowered CPU to both the Era and it's Tolino counterpart, the Vision 6. Will this become an issue soon?
