Assuming you buy quality stuff at the beginning, it doesn't matter at the end of the day what name is on your tent, sleeping bag or rain jacket. You can wear boots or trail runners. The trivial stuff tends to occupy much of the planning in retrospect and you can see it sort of repeat every year on this forum with the questions that get asked..
Best thing I did in preparation: went and talked to some former thru-hikers in person. This site is great but too much conflicting opinions (which just proves that there are multiple ways to do this thing). Good luck on your hike. It really is a great way to spend 5-6 months!
