You are lucky man, my wife resigned recently & moving from Big 4 to another Big 4 but they could not retain her with 30% hike! Check the retention offer - it might be retention bonus & not a fixed salary hike!! (I guess you were definitely underpaid, since 50% hike is a bit difficult if you are moving or retaining at the same level).
My rule is never to stay after resigning
Any specific reason?
