Which is the best and why???

Why USA use an old TV system? Why not PAL?

Answer 1

The USA was first in the world to launch a colour TV service , the only available system was NTSC ( sometimes called never twice same colour ) . The PAL system was a development of the NTSC and came too late for the USA who had NTSC in full swing. Europe , Australia New Zealand etc were lucky enough to get the PAL system ( A little patience sometimes pays off ).
Without getting too technical the bare bones of the PAL system and the key to the better pics lies in the way that PAL stores in a delay line each line of colour information which is then compared to the next line, now if any colour errors have occured due to transmission faults or phase changes which affect the hue or colour then a signal is added to the next lines so you end up with an average of the original picture, hence the initials of PAL mean phase alternating line.
Main difference between a PAL set and a NTSC is a lack of a delay line in the NTSC. After all that to answer the other part of your question . PAL is superior to the NTSC system . Cheers Pete

Answer 2

I don't think there is a real big difference. its more or less the difference in standards made for the differing countries. They both give about the same quality of picture. the difference in quality of picture will come from the addition of "Progressive Scan" or "HDTV" TVs. Progressive, the lesser of the two, uses an alternating system of the lines of resolution on the screen, creating an almost no-lines-of-resolution view. HDTV uses a similar system, although more and more of HDTVs are being made from LCD and Plasma screen TV's that use liquid filled screens that dont have "lines of resolution" and have more crisp and clean looking images
