E402 vs. Boron (please give opinions)

I have purchased an Electron E-Series E402 evaluation board. I like it. It seems more stable than the Boron but I have miniscule testing experience with it.

All I care about is stable, permanent LTE/cellular

Is the E402 better than the Boron?

Are there opinions on this topic?

It is obvious more difficult to use the E402 because you need to make your own PCB. It is also a bit more expensive and has less memory.

But I don’t care about any of that. I just was something that is not so electrically sensitive, fragile, and “maybe/sometimes it will work well” as the Gen3 Boron.

Does anyone have experience with both products?

Thank you.
