Which would you choose?

OK, kinda unsure if this belongs here so if it's in the wrong place, my apologies. I thought that Theory was the place that best fit.

You are granted one of two abilities whenever you are playing poker. These would apply to playing any game that uses community cards. The choices are-

<font color="blue">1) - You will be able to know all opponent's hole/down cards in addition to your own from the time they are dealt. Your opponents will not know that you know this. You will not have the ability listed in #2.

2) - You will be able to know all community cards that are coming preflop as soon as all players get their cards and before any action has started. You will not however, be able to know what your opponents hole cards are (unless you make a regular read of course). Again, your opponents will not know that you know this.</font>

You can only pick one and picking that one guarantees that you will never have the other.

Which will it be?
