I have owned and run several businesses from small to large, wholesale and retail, including a small restaurant. Only you can decide which location you want to use but here is what I would recommend you consider.
Snacks are not something people seek out. They are impulse and you need foot traffic or a slow traffic area. In the restaurant business surrounding competitors actually helped business. I would assume it would be the same in the snack business. You need to spend some time monitoring each location for "traffic count" at the snack time of day. Middle of the morning, middle of the affternoon, and evening. Of course Filipino I guess is 24/7 lol. Location and exposure is everything in retail. You need to have the biggest "face" (signage and display) to the traffic as you can and go with the higher foot traffic location.
