It's more "neat" to use uppercase letters as decimal digits are "uppercase" as well. Then again, lowercase is generally more readable (that's why lowercase exists in the first place). Thus, there doesn't seem to be a clear-cut answer.
The great debate
I came up with a better system in under 10 minutes.
You are retarded. Your symbols make absolutely no sense. The symbols of the user you responded to make actually perfect sense if you are not a nigger.
It makes perfect sense. Count the vertices you dumb nigger. You're just name calling because you couldn't think of such a simple system in such a short amount of time and are jealous as fuck.
Usable symbols need to be instantly recognisable and not require ridiculous procedures like counting shit.
None of the symbols you posted are anywhere near the realm of 'instantly recognizable', your argument is invalid. It's based on completely arbitrary logic and if you flip it upside down it becomes even less recognizable. The entire point of a symbolic system for hex is to preserve the information, not read it quickly. What difference does it make whether you can recognize it instantly or not? Absolutely zero. Take your 20 IQ back to reddit please.
You mean binary?
Yep, you're a nigger.
If written by hand it would help to add some form of notation or differentiation to 10-13 otherwise you could end up with some ambiguity.
You're retarded.
stay mad forever brainlets enjoy your inferior hex symbols dumb fags
Learn binary you stupid nigger.
