Because of the way the prop turns, if all else is equal, you'll get a better wakesurf wake on the left side of most inboards. The exception is Correct Craft since their props turn in the opposite direction of most. In their case, the right side will produce a better wake. However, the difference is not very noticeable.
Rather than let your boat's prop dictate which side of the wake you use, you're most likely going to want to weight the side that you're most comfortable on. This is usually the right side for goofy footers and the left side for regular footers.
