I don't think the U/B control deck is a good option for the average player after this event, and I can't wait to crush all the 'unknown pro' players that start running it at FNM and IQs around here. It was a meta call by team pantheon, that becomes a lot worse once it's a known entity. Control beats midrange, enough so that even a 'bad' control deck has a big advantage. This field was full of midrange and it still didn't win.
The Esper deck that barely missed top 8 is a better choice if you have to run control, as it had better matchups against everything except the U/B control. Or, personally, Jeskai control seems legit. Cut the mantis riders and rabblemasters for end hostilities, a couple keranos and more removal (banishing light, singing bell strike, devouring light, pillar of light, etc..). Dig through time is a good enough card advantage engine, and using your burn to close out a game quickly instead of slowly grinding it out. Oh, or maybe you have a transform sideboard with 4 mantis rider and 4 rabblemaster and switch into jeskai wins when they board out their removal.
That said, jeskai wins or a abzan midrange variant are clearly the top 2 decks for now, but the next best decks are VERY close. The difference is less then the normal difference between a tier 1 and tier 1.5 deck. Jeskai combo, mardu midrange variants, R/W tokens and UWx control are all in the mix and may be advantaged if jeskai wins and abzan have targets on their head.
