If I wasn't having a bad day before choosing ATSC I
Certainly would be afterwards.
The whole world except 2 countries uses COFDM
in one form or another for DTT.
Can't you see who's out of step Doug?

To reply to the subject line,
I would choose whichever system gave the most bits at with the least
problems with digital into digital co-channel and adjacent channel
interference.
This chooses ATSC over DVB-T.
The reason is simple. A really bad day is one in which tropo ducting is
strong. This fairly frequently causes, where I live, bad adjacent
channel interference and more rarely co-channel. The 3 dB interference
advantage of ATSC can really help.
