Honest truth, I have the 8GB model and use it everyday with zero issues. Multiple apps open, streaming music, pics, etc. Does it all with relative ease. The occasional hickup with screen rotation but otherwise no problems. To compare, I own the Moto X Pure (2015) and side by side I see no difference browsing forums like this one or doing normal daily things like text, call, and email. Storage is the worst part. I can't put all my Moto X apps on here but maybe that's not a bad thing. Once 6.0 hits our devices I'm sure the 32GB card I have in the Moto G will be the primary storage.
Edit: the battery life is FANTASTIC. that alone is the primary reason I use it as a daily over the Moto X.
