For my group, it does depend on which characters are at the meals. I've done Storytellers and PCH Grill and my group would lean towards PCH Grill because the characters are more familiar. The most commonly mentioned characters are Mickey, Pluto, Stitch, Daisy, and Minnie at Surf's Up at PCH Grill. Over at Storytellers, the mostly commonly mentioned characters are Chip & Dale, Koda & Kenai, and Meeko. I thought both locations had good character interactions (the characters came to our tables, posed for photos, signed autographs, and were generally friendly). I went to Surf's Up with two small ones and they liked it and the characters were familiar. Based on how they reacted in the parks to characters they were not familiar with (e.g., who is that? "I don't want to wait to meet a character I don't know" or "I don't know that character and I'm scared of him!"), they probably wouldn't have enjoyed Storytellers as much because they wouldn't have recognized Koda and Kenai.
