Question

Who got the better of it compromise of 1850 and why

Answer 1

Welcome to Openstudy.

Answer 2

The North got the better deal.

The south got out from under the Wilmot Proviso and the agreement that New Mexico and Utah territories would get to choose for themselves whether not they would have slavery rather than have Congress decide, a stronger fugitive law, and preservation of slavery in DC.

However.....
New Mexico and Utah were mostly populated by non-Southerners who were not inclined to vote slavery in; while slavery itself was legal in DC the buying and selling of slaves were banned; Southern California remained free; no guarantee of slavery south of a territorial compromise line like the "36 degrees 30 minutes" line of the 1820 Missouri Compromise that if extended to the Pacific would have made slavery legal in Southern California and New Mexico.

So other than the strengthened Fugitive Slave Law, the South pretty much lost out on everything on its "wish list".
