I will keep my wireless.
There is nothing inherently more or less accurate between a wired and wireless bike computer. They both have pulse generators and a time base clock that use a user set wheel circumference to calculate distance and speed. Typically you get one pulse per wheel revolution and if the pulse it received by the reading head, they read identically. The only problem with wireless is stray RF can interrupt the pulse count or add to it. If there is no interference or the computer is made to ignore it, it reads properly.
