I have been watching TV more carefully, and progressive content looks very 
clean, although my TV is interlaced. There are few artifacts, and hardly 
noticeable. No jagging, only a bit of blur here and there.

But interlaced content is different, it's not only jagged, it also make 
scanlines much more visible. And IMHO, scanlines are nasty. Anyone that have 
used an emulator would know them. Interlacing also make borders fuzzier.
