I’ll get it started. I just had Aldi noodles for the first time and they were pure shite.
So…Lidl is better for cheap noodles (the 5 pack ones are very decent at only 30c a pack in the 5 pack).
Aldi has a far better frozen section generally IMO.
Lidl is better for almost anything. I used to be a hardcore Aldi (Nord) loyalist until Lidl started having a very good vegan selection and better hummus. A couple years ago I probably could’ve named something I miss from Aldi, but at the moment I genuinely can’t think of anything except that I remember their selection of local-cuisine-themed sweets to have a slightly better selection. When they had a Spanish week some months ago they had Almendrados, which is something I’ve never seen a Lidl carry.
But I think this highly depends on where you shop and what you need/are expecting a discounter to carry.
In the Netherlands we only have Aldi Nord (didn’t know about Sud before I went to germany), and have visited them less and less over the years. Lidl has been expanding a lot the last 10-15 years and I am becoming more and more a loyalist. Aldi (Nord) to me is really losing the game in my eyes.
