Hi, there! I think this depends on your personal use case. The Samsung Galaxy A series offers affordability, solid battery life, and decent performance, making it ideal for casual users. It features AMOLED displays, plastic builds for durability, and capable cameras but lacks flagship-level processing power, premium materials, and advanced photography features.
The Samsung Galaxy S series, however, delivers top-tier performance, superior cameras, and premium build quality, considering it is Samsung's flagship series overall, making it perfect for power users and professionals. The disadvantage is that it may not be affordable for everyone. Although it also has some hardware slightly lower battery efficiency, and is more fragile due to its glass construction (depends on user's care and handling).
So if one prioritizes budget and longevity, the A series is a great choice. But for peeps who would prefer a unit that excels in performance, and photography, S series is a great choice.
