Much better than the other one so far. GPS works perfectly. I went to a local spot where I frequently lost data and it switched to 3G and stayed connected. Funny thing is, I have only dropped data once so far and that was literally after I unboxed it, powered it up and used it for 5 mins. I connected to WiFi, the 4G came back and it has been connected to data since then.
The real test will come next week when I am travelling, fingers crossed!
