Tuners

Steinburger 40:1 locking tuners or Planet waves 18:1 locking with auto trim. Okay, technical question, if you had to choose between the Steinburger or  the Planet waves with auto trim, which would you choose. I like the self trim tuners, they are really easy to change strings as you don't have all that wrapping etc. The Steinburger have a higher tuning ration of 40:1 , but do not have the auto self trim. Which would you choose?  

Does the 40.1 vs 18.1  really have any real impact?
