E5823 vs E5803?

[Soundtallica]

I'm thinking of picking up a Z5 Compact for my switch to AT&T. But which model should I get?

I already know that the E5823 supports cat 6 LTE while the E5803 only supports cat 4 (which I don't care about) and that both models will work in the US, but I'm more curious on the software update front. Since the E5803 is obviously an older batch, will it get updated less frequently and have less dev support than the E5823? Are mods and roms between the two models different?

I'm only asking since I can get the E5803 for $20-$30 cheaper on Amazon and is eligible for Prime shipping, while the E5823 is more expensive and doesn't have Prime shipping. I'd like to go the cheaper and faster route if possible.

I think that's hard to say. Just because a particular phone model is more recent doesn't mean it will be updated for a longer time. For example, if that later model is more of niche variant (with lower production numbers), that might make it less likely to be kept up to date by Sony.

I noticed that too, I'm glad that you made this thread. It's kind of weird that they have just about the same bands for each model. From what I saw, one has a U.S. warranty and one doesn't. If you care about warranty, go with that.

Appreciate the above response.
