Funny, it's the exact opposite for me. All our other stores also have their own standardised layouts and I have a far easier time remembering those than Aldi's, even though I've been to Aldis far more times that some of the other ones.
Checkout is immensely infuriating for me because it's clearly focused on getting me out of the way asap. I'll be standing in like for 10 or more minutes, then get rushed through checkout at a ridiculous speed. There's like 10cm of counter space so products start falling if I'm not putting them away fast enough. I have to put everything back in the cart and then sort things into bags to take home at the awkward shelf at the exit. It's efficient for them, but inefficient for me.
And I do actually like some choice - sometimes I want a cheap tomato because it's getting cooked or put in a salad anyways and sometimes I want the better more expensive one because it'll be used "raw" like on a sandwich.
As for packaging, I was talking about retail packaging. Like, in a regular store, even a small one, I can ask for X dag of sliced cheese and I'll get that much in a small light wrapper. In Aldi, it's pre-packaged in hard plastic of an unreasonable size and I just have to buy multiple packs if I need more cheese. Same with everything else, even some vegetables. Even cans are shrink-wrapped together sometimes! I legitimately observed my bins filling up far quicker during the time I used to always shop at Aldi.
