I agree with you both. Raghav's emotions have more clarity - they are shown in more detail. Be it his loneliness, his bias, his selfishness, his ruthlessness, his pain. Everything is clear. He hiding his softness behind a tough exterior is also clear.
With Pallavi, apart from her undying love for Deshmukhs, and her kindness, we haven't been shown much about her life and what she has faced. Woh kahawat hai na, "Shaant pani gehra hota hai". Pallavi is that mystery waiting to be solved by Raghav Rao.
