It’s not hard to brew a Pilsner, and brewing your own beer is rewarding, but the light German styles are the hardest to really improve on. If you just put some quality ingredients and decent temp control fermentation at a Pilsner, you’re going to get a super great beer judged against some regular commercial offerings, and a good beer in general. To get better that that, look into LoDo brewing if you want to go down the rabbit hole.

If you like to strive for perfection, the german styles will scratch that itch for you.

Edit: I will add that brewing Pilsner or Helles will literally never impress your friends. You’ll get a shrug and a “oh that’s good” out of them when you’ve put your heart and soul into driving out one little off flavor from your ferment that no one else can taste but you. IPA is basically the polar opposite.
