While most of what you've said is rather terminology reference oriented (one man's "warm" can be completely different to someone elses), but the 193 having "more shine to the top end" is COMPLETELY the opposite of what I've experienced comparing the two.
The published frequency response charts alone will tell you this... And is confirmed by listening to them.
Oddly enough, that's where I have a hard-time with the 193... Its pretty darn lifeless to me.
I love my 103s as overheads, as bgavin pointed-out... They do their job on acoustic guitar, and they either work great or don't work at all on a vocal.
