I would argue penlights have their place as a style item. If you want to carry a light on your person, but doesn't want to visibly bring an EDC.
A Copper penlight in a shirt pocket is certainly a choice I would care for.
I have a couple Sofirn SF15 lights, mainly for its dual purpose White + UV options. It's not the best for anything, and it runs through batteries (Eneloops) like nobody's business on High, but it does the job in a very inconspicuous package.
As far as penlight options go, I would stay away from the Acebeam Pokelit AA. The tint is excellent, but the modes are either a too low Low, or a too high, thermally unsustainable High, and with nothing in between.
There is also the MT2A Pro, which has that Middle mode, but the tint on that thing is green and butt ugly. I personally didn't like beam pattern at all either.
I once bought a Streamlight Stylus Pro as a gift for my cousin when he was about to study overseas, and while I haven't seen in use, the design felt too "tactical" for my liking.
But there are tons of penlight options out there, so there definitely seems to be a market for them overall.
Can't speak to the brand, as it has very limited availability here in Norway, but the Wuben E19 in Blue seems nice design wise. And it comes with a hCRI LED which I definitely prefer over some high-power thing. The SOS seems a bit redundant, as a penlight in my view is something used to navigate the hotel room without waking the missus - or navigating the missus without waking the neighbours.
