My personal go-tos are Shan and Deep (I really like the Shan garlic pickle and the Deep lemon and lime pickles; they both make competent mixed achar). If I can’t find either of those, I will settle for Patak's over other brands I have not tried (there are some I have tried and Do Not Like).
Pataks aubergine pickle is great though. One of the simplest ways I like it is spread on wholemeal toast, and topped with hummus. Bringing India and the middle east together on some bread. Their green chili pickle is decent too.
Edit: I'd actually take those two Pataks versions over the Shan equivalent.
Patak’s will do in a pinch if there’s nothing else but I don’t like the smaller size of their jars and the lack of variety. I agree the Shan versions of those you cite are not particularly distinguished. They offer some unusual ones like lasora but for things like amla which are usually not pickled in Muslim community you are better off with another brand.
