Does the tbs6909 have the best tuner?

[nightshadow36]

I bought 6 x tbs6985 cards 2 years ago when i first strated learning about iptv. Had nothing but problems with them. Tuners stop working high Ber Etc.
I will be wanting to upgrade all my cards.
Is the tbs6909 the best model at the moment better than the 6905 or 6904.
I am looking fot the best tuners for signl strength / quality / hardware.
Thank you

6905/8 is better because have STm STV6120/STV0910.

6904 = 6985 (same tuner/demod AV2011/TAS2101)

6909 is very specific product, for IPTV streamers .

Ok bought 2 x 6909 before i saw the reply and i think i have made a mistake.

So 6905 / 6908 are the best.
Is the 6909 a good card and tuner? Is it a card that will have problems with receiving good signal and being stable.
I am using them in Ubuntu with Astra cesbo with i think your drivers the open source drivers and then stream to Xtreamcodes.

Test channel = Channel 5 using Astra Cesbo
Card 6909 Signal = 53% SNR = 50%
Card 6905 Signal = 62% SNR = 50%
The SNR is the same and the signal is a about 10% less on the 6909
Now the difference in signal is that due to the Card Tuner model or the Driver? And how to tell if the values are correct?
I do not have the best sat signal as it is so its important to have a tuner that works the best.
I was searching for the tner model but could not find it listed under tbs or on the data sheet
Thank you

Percent values says nothing about real signal as signal is not measured in percents, but in dB. Drivers do some calculations to recalculate dB to percents, but for different models You will get different results because of HW differencies and lack of ability to recalculate signal measures in the same way. So differencies in percent values can be ignored.
Same situation is in standalone receivers - if You put two receivers - different models even from same producer - they will show different percent values, but that doesn't mean that one is better and the other one - worse. Only way of comparions would be when both receivers would show raw dB values from demod.
