I disagree.
It is not so black and white (excuse pun!). Here are a few pointers.
PVA screens are used by Sony and Samsung and have good viewing angles and contrast. However Apple specify only IPS pannels as used by Panasonic for their colour accuracy.
Backlighting can account for up to 40% of the net cost of a lcd and manufacturers are deparately trying ways to reduce this. I have read plenty of negative comment about the wide colour gamut lighting used by samsung.
The Samsung wiselink may be useful to you.
I dislike the styling of the Panasonic 60 and think its more expensive brother the 600 has better styling. It also has better picture processing. Both Panasonics have a very good remote. The 600 has very good sound much better than the Samsung.
Panasonic also score higher than Samsung on Reliability.
Personally I wouldn't buy anything until I had made my own mind up. You need to do more homework until you are happy with your choice and buying somthing because someone on a forum told you it was best is not the way to do it.
There's somethings you dont know about S-IPS and its not black and white like you said.
S-IPS is poor for viewing compressed videos, especially the ones converted form Film to Digital/low bit rate. Now, as you may know, S-IPS and VA (PVA and MVA) have very slow response time when compared to TN. So to lower the response time below (<16ms), manufactures use a technology called "Overdrive". Overdrive is a name for increasing amplification on the pixel voltage rails.
On S-IPS, overdrive causes elevated twinkling effect in movies and pixilation on highly compressed videos (Sky SD, Sky HD, Freeview etc
), which can be annoying and it causes dithering (only if overshoot occurs) on VA panel.
The following information is quoted from my guide:
Something to know about IPS LCD panels!
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
S-IPS LCD technology is currently manufactured by LG.Philips and Chi Mei Optoelectronics. S-IPS is designed for static viewing. In other words, it was designed for photo editing, medical use and public displays thanks to its wide viewing angels and outstanding color quality but its slightly poor at displaying movies and compressed videos (elevated noise levels). Its black levels are also quite average but, its response time is excellent.
Overdrive:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Overdrive was invented by various manufactures to lower the repose time by increasing voltage/amp levels on LCD panel. If the overdrive mechanism is incorrectly configured or over used, it would sometimes cause pixel to malfunction permanently or prevents it from fully turning. In most cases, overdrive will cause image retention, dithering and twinkling effect on compressed videos. If image retention occurs, unplug the LCD from the mains for 24hours before use.
Dont get me wrong, S-IPS used to be the best, because the rival PVA and MVA LCDs are quite poor in comparison (lack of color and viewing angles) but since the introduction of S-PVA by S-LCD (Samsung-Sony LCD), S-IPS lost its crown. S-PVA provides better color (still slightly below S-IPS), increased viewing angle, higher contrast ratio (with deeper blacks) and its only one of two panels what made LCDs closer to CRT and PDP.
S-PVA also has slight twinkling effect due to overdrive but its not bad as S-IPS.
The primary problem is S-IPS is its black levels as black may appear grayish. This is why S-PVA is recommended for best picture.
Here is a simulated twinkling effect (pic noise) and overshoot.
