Whats better Manual steering or Power?

ive had manual in my 69 dart with BB for about 10 years. i guess im getting old. i really dont like it anymore. the duster is power with 245 45 17s all around, no way is a manual box finding its way into it. id likt to go with a firm feel power box though. i drive it daily in the warmer months. i find it to be very relaxing driving that car, and fter a hard day at work, it dont feel like playing with manual steering. i dont know about manual beeing one less thing to worry about, i went through 2 manual boxes on the dart since swapping over. they were tight when i put them in. i never killed a power box in anything.
