my heart is for samsung 1st b4, but now when toshiba 42 inch fullhd with price below 3k, i think toshiba give better, but at the same time samsung b530 is the best lcd so far
Why do you say B530 is the best?

In fact it is actually the lowest spec fullhd from Samsung
Samsung has series 3, 4, 5, 6, 7, 8, 9 for LCD; 3 and 4 are non-fullhd; 5 to 9 are fullhd
Which means, Series-5 is the most "basic" fullhd LCD from Samsung, similar to Toshiba CV series (same price range as well)
Normally, entry-level LCD like these have the lowest spec among other series and not much features and image enhancement etc. There will be fewer HDMI ports and other input choices, no USB port for photo/video playback, and lack of picture tuning/calibration settings etc.
Next up from Samsung is Series-6 which I think is more in-line with Toshiba ZV series. Since RV is in between ZV and CV, it fills a gap left by Samsung between Series-5 and Series-6 (something like 5.5)
The closest model from Samsung comparable to Toshiba 42RV600E is Samsung LA40B550 (has USB port for media playback), but RV still wins by size (42" vs 40") and slightly lower price
Another contender here is LG 42LH35 (has USB port for media playback too) if you like Korean brand and prefer 42" instead of 40"
