Clickbait title, but an interesting topic. The mindset of players tends to affect their playstyles, and therefore their ID choices. Playing Kate isn't "lazy", it's calculated and precise. Unless you're playing KC's Kate you can't afford to go gung-ho and slam your face into everything because you rely on event economy, which is limited. You rig up until you can threaten any remote at any time, then take advantage.
Contrast this with a criminal deck. Facechecking HQ turn 1, click 1 as Gabe can provide information and money. Sneakdoor makes the corp have to defend on two fronts. Account Siphon is a card that exists. You make moderately risky plays for a potentially massive reward.
Minh Maxx is similar, but with an alternate win condition of DLR. If anything it's a happy medium of threatening siphons/denial and installing lots of cards that lead toward inevitability in the mid-late game. You have to know when to do which, and that's hard for someone who's been playing on either side of the spectrum almost exclusively.
I'm a dyed in the wool crim player and I have trouble piloting the thing because I'm terrible at stopping to install cards. I don't like not running every turn, but Minh MaxX requires that you know when to pump the brakes and slap down three Pavilions. It's an amazing deck and does disgusting things, but it's probably not for me. The same is true of your friend for opposite reasons.
TL;DR, it's not laziness or recklessness that makes the deck hard to pilot. It's that the deck is well designed and requires different piloting skills to fully utilize its win conditions.
