I have been a Lidl shopper for a couple of years now. The nearest Aldi was a very grubby one. Recently a new Aldi has opened even closer to home and i am in the process of deciding which products are best in each store. So the shiney new Aldi is more convenient but, i am used to, and a little loyal to Lidl.
Lidl and Aldi have their own brands but Lidl also stock some more recognisable brands also. They have increased the offer of known brands, i believe in an effort to encourage a 'fuller' weekly shop from customers. Aldi's offer is only their own brands.
Aldi also pretty much leads on price. e.g. Aldi sell 1l skimmed milk for 85c Lidl reduces their one to 85c, Tesco took about 4 weeks to cop on and theirs is now also 85c. (i'm in Ireland BTW)
Both stores are good for veg, far better and fresher than Tescos. I think Lidl have a broader range of veg. Aldi's Super 6 are excellent value, and they are a moveable feast. If any other store undercuts them, they undercut again. Instantly. This led to a fantastic price war before Christmas over here. Was it the same in the UK?. Pineapples 15c, Melons 15c bags of brussels 15c. Because of this policy they have stopped printing the Super 6 prices on the leaflet because they reduce them daily depending on what the competition do.
Tesco meat is overpriced and vile. Both Aldi and Lidl are good for cold meats, parma ham, choritzo, ham etc. My butcher is always the best value for my fresh meat.
I would much prefer Lidl's offer on toilet paper and kitchen roll. Quality and quantity it is much better value than Aldi. I have tried both washing tablets and found Lidl to be much better than Aldis. (I use one to boil my kitchen cloths on the hob and you can see the difference, the lidl one froths and cleans.
I have yet to try Aldi's pasta, rice etc. But I have used and would recommend Lidls egg tagliatlle, basmati rice, cous cous. Great value and excellent quality.
Aldi's bacon (rashers) are the cheapest and the tastiest. Aldi also has a great Greek yoghurt. I have switched tin foil and firelighters to Aldi aswell.
Cheese is excellent in both stores.
Aldi's baking section is very good. Spices in both stores are good.
Because Aldi leads on price, I will do as much of my shop in Aldi's, then Lidl, using their special offer leaflets as much as possible. I will use coupons and deals and a few rare brands in Tescos or Dunnes Stores.
OK I'm begining to bore myself now. Sorry.
