The regular Quick Looks are just the Giant Bomb crew playing through the first 20 minutes or so of a game, while the Quick Look Ex are when they’ve invited the developers of the game to sit with them and explain.
There really was an awful lot of whining around this episode, but people are mostly concerned that it won’t be an equally accurate when invested people try to sell the game at the same time.
Not that Plain Sight needs that, but there have been exaggerations and a bit too much selling going on from other developers in the past, so they probably just want the undistracted reactions from the crew.
...But like I said: there was an unusual amount of whining this time…
