Is Aldi like Trader Joe's?

I'm curious to know, how does Aldi compare to Trader Joe's? Are they similar in terms of their product offerings, pricing strategies, or customer service? I've heard that both chains are known for their affordable prices and unique product lines, but are there any key differences that set them apart? As a shopper looking to save money while still enjoying quality goods, I'm eager to understand the nuances between these two popular grocery retailers.
