So as according to @andrewboydston, Top Hat is good when you are accessing cards with the knowledge that YOU KNOW what you are accessing, otherwise it's just another random access.
Well folks, thanks to Reign and Reverie, I present you ladies and gentlemen, INSIGHT =)
With Insight, runners are now able to SNIPE that agenda without double running R&D which is kind of suicidal against the new hot Corps of lobstermodernism Argus and the sneaky Mti who can install ICE on the fly despite being once per turn. Also, multi runs in the recent meta is very punishing for the fact that you need to respect the new Econ Warfare > HHN > HPT combo turn and also spending a huge amount of boon you looted just to score that one agenda.
Despite giving the Corp a chance to re-arrange what they can draw for the next 4 cards, Insight also allows you to LOOK AT the top 4 cards that the Corp just arranged. So if there's no agenda, treat it as a blank Indexing you just made and chill out to make the sniping run for agenda without breaking a sweat on R&D.
Oh, and what if the Corp ICE up R&D when they see this coming? Great! Now you have slightly vulnerable HQ or scoring remote to break in then.
Did I mention Top Hat is only 1 influence? So for each Insight and Top Hat pair, that's the same influence you spend on Indexing! Top Hat is also a hardware, so perhaps you might only need to land 1 on the board and only 1 or 2 copies will go into your deck. Although theoretically you are spending a slot of two for this pair, but it really doesn't matter as long as it wins you the game. A calculated risk and sure-fire agenda scoring is better than suicidal multi runs which would lose you the game.
In a nutshell, I can see Top Hat coming back from unplayable to super exciting card to see in the meta! P/S: Sounds like I'm reviewing Insight more than Top Hat. Jeez
