Deciding to buy, rev hang and throttle response?

Hey everyone.

Looking for a second manual to pair with my Mk7 GTI DSG. At this point I really have my eye on an MT Neptune Blue 86, if I can find one. I've test driven a BRZ, and just today an 86, and two things are really making me second guess. I noticed both times a really significant delay or dead zone in the throttle, and today a really significant rev hang. Could not get a feel for shifting, downshifting, and setting off. It all felt so vague. I know the car is well loved, how do you guys feel about these things? Did you get used to them? Are they in your opinion things to rule this car out? I'm kinda bummed, I love the car in every other way, so I'm not sure what to do now. Either way, I can tell it's going to be a journey finding an MT in Neptune, so I have time to think about it.

Thanks for your input!

Also, I'm aware of the Pedal Commander that lets you remap throttle, so I know there's that route too.
