I use Google Play Books as my main reader on Android and iPad Mini devices. I buy from various sources, process into Calibre and then load into GPB for reading.
I find the interface fine, and it does sync across those devices, but not my Sony PRS-350 obviously. I did use the Sony app too, but when they shut the library I tried the Kobo app and thought it was rubbish. The smallest font is far to big and the font selections are ugly.
The main thing is to put the books into Calibre so I can load them to whatever reader takes my fancy in the future
