If we were to compare both of their most recent lakorns, Taew in Dong Poo Dee and Vill in Sakul Ka, Taew takes it all. Vill is still weak in acting, her crying is okay, but her acting needs more concentration. Vill has problems with her eyes, they're so empty and seems like they cannot focus which makes her acting very weak. Plus, Vill only has one look, that innocent puppy face which hasn't shown much versatility at all. Taew nailed it in Dong Poo Dee, she's proven to be a great actress. Her tone, body language, facial expressions, everything coincides with the right emotions.
Let's say, if we were to exchange the roles, Vill as Khom in Dong Poo Dee and Taew as Dao in Sakul Ka, I believe Taew would also nail the role very well versus Vill, who may portray Khom loosely and weakly. Nothing against Vill because she hasn't had much time to act and expand her abilities but in this comparison specifically, without any bias, Taew.
In terms of personality, I would have to give it to Taew as well. She knows what she wants, she has concrete answers to all of the questions, she's not fake, and she's very down to earth and humble. As for Vill, at times, I feel as though Vill listens too much to what the elders have to say, she doesn't have much room to show us who she really is. So Taew.
Looks, at first Vill was pretty but the longer I look, the less attractive she becomes, no offense. She looks older than her age. Taew is the complete opposite. At first, I didn't think anything of Taew, she wasn't that pretty, she was okay but the more I watch her, the more attractive she becomes. She grows on you beautywise. Not only is Taew cute but she can also pass as pretty too which is hard to find these days. So Taew.
