It also isn’t the most useful thing to ask. I’m a developer, but the box I’ll be installing bluefin on isn’t going to be used for development. 
Do you want development tools would be more actionable.
I think this is going to be tricky. I’m new to linux on the desktop (have maintained a few lowkey web servers) and I know enough to want to make an informed decision, but the information I’d be looking for will be meaningless to others (and I’m having to research to even understand most of it - whatta nerd).
The overall focus feels right to me, especially as things are pretty young (cboot hit 1.0 like a month ago or something) but it’s good to not get locked into a perception of your product either. Bluefin is only for devs - someone could just want a nice stable OS to do various things on. Bazzite is only for gaming - someone could choose it for a daily driver for casual computing that -also- plays games and bazzite makes that simpler. Obviously it’s good to focus on their strengths to differentiate, but they’re also more flexible than that.
Perhaps a table above or below the cards for each distro on the main ublue site:
New to Linux or wondering which flavor of ublue is right for you?
| Distro | Stability | Gaming | Everyday | PC | Handheld / HTPC | Appearance | Coding (optional) |
|---|---|---|---|---|---|---|---|
| Aurora | A- | A | S | S | N/A | Windowsish (easily customizable) | General Dev |
| Bazzite | B+ | S | S | S | S | Windowsish (easily customizable) | Gam Dev |
| Bluefin | A | B | S | S | N/A | Macish (more opionated) | General Dev |
| Bluefin GTS | S | B- | A | S | N/A | Macish (more opionated) | General Dev |
Maybe have a column of windows or mac familiarity based on DX. Like bluefin is A tier mac and A- windows, aurora is S tier windows or something.
That would help people make a quick judgement of which one to look into.
