Glad to see r/dumbphones over here! I'll start:
Current phone: Sunbeam F1 Orchid
I picked it because it was one of the few dumphones that didn't run KaiOS (can't trust it) and didn't have Google's claws in it (as far as we can tell). There are surprisingly few dumbphones that also have a focus on privacy. I've looked into the Punkt and Mudita Pure, but I've read too many horror stories about buggy software.
My ideal phone would be a reincarnation of the Blackberry Curve (preferably not running Android, although a stripped down AOSP is ok). Unihertz comes close, but the ability to put modern apps on it ruins it for me.
I also have a separate Garmin for travel. The Orchid is fine for what it is, but traveling is much less stressful with a dedicated GPS device.
