You are forgetting their age differences. Loria is 12yrs old but comparing to the other kids of her age her singing is quite ordinary. In that aspect Vaishali is way better than her. Loria's voice trembles too much. It became very evident when she sang 'katra katra' and Sonu pointed out it. She has proved that at 12, she's as bright as a 17yr old(she's passed 12th). But i should say that she doesnt have that much talent in singing.
I agree that their age differences are huge and during this period a difference of 2-3 yrs is a lot..Vaishali is 10 and Loria is maybe,13.Keeping the age factor in mind,Vaishali is way better and when Vaishali is 13,she cld beat Loria hollow....
But unfortunately,currently,the competition format doesn't differentiate between age groups...All kids,aged 7-14 come under this category..When they have been put under one category,they will have to be judged equally...We shld presume,that we dn't know the age/face of these kids and only listen to their songs...On that basis,Loria was better.For eg)when Loria passed her 12th coz she was good,not becoz she was a 12 yr old competing with 17 yr olds....Hence age,unfortunately,is not a criteria here as per the rules of the competition. 😊
