I have been using the Moto G 1st Gen for almost 3 years now and have to say that I am absolutely pleased with it. It somethimes switches off for no reason, which is annoying, but acceptable for such an old phone.
The design is good IMO, the display quality is still very nice and the plastic back doesn't increase slipping.
Apart from better pictures there's absolutely nothing I really miss about it.
It actually makes it pretty hard for me to find a phone similar to as it was back then now.
