Lanka are strong early on, while Kailasa is strong late game. This makes a blitz very unbalanced in favor of Lanka imho.
It you manage to last till you can summon Gandharvas and build lots of mage priests, Kailasa can win, but not against a rush.
I once played a Ramayana game myself, and Kailasa won because I wanted to see how the late game summons were, Lanka happened to have a crappy starting location, and I toyed a lot. So the game lasted longer than it should have due to 'let's try seducing with rakshasi' and 'I want to see all national Summons', which led to a big advantage for Kailasa late game. Early on, they suffered more than a little.
