Tamboli's reason wasn't the brightest - i.e. the kachra, but it wasn't like the other team's garden was conceivably beautiful - it wasn't. Had she chosen theirs, Team B would've been more than justified in chanting bias too. So ultimately - it came down to a tough choice, which she justified poorly.
Personally - Team Punnu, despite being one player less, performed better hands down, and deserved the win fair and square.
