The deal was actually massively favourable to the US. The missiles in Turkey were already obsolete and extremely vulnerable to a first-strike (liquid-fuelled, close to the Soviet Union).
With solid-fuelled ICBMs like the Minuteman coming online, and the first Polaris SLBM patrols occurring around this time, the US wasn't really sacrificing anything, whereas the Soviets were sacrificing their only realistic first strike capability on the US. They had to wait until the 1970s and the Delta class submarines came online to get something similar. Essentially, the Soviets backed themselves into a corner, though they did come out of it with a guarantee Cuba would not be invaded
This video below, from a documentary about the US Secretary of Defence from 1961 to 1968, Robert McNamara, has a very good overview of the Cuban Missile Crisis (from 6 minutes 50 seconds in).
I couldn't recommend it highly enough for anyone who is interested in Cold War history
