Snapdeal has better prices on a few products, but the overall experience isn't any better (wrong products being shipped, customers cheated by soaps/bricks in product cases). Flipkart/Amazon prices are a little higher but the overall experience is better. Both offer pretty good support as well.

Flipkart is technically more impressive than Snapdeal. (Flash sales/in-house hardware, etc). It has it's own brand similar to Amazon basics - DigiFlip, some of which are of decent quality - cables, chargers, etc.
