There are so many finishers out there, and they all work. Some may give a smoother shave or a slightly keener edge, but I really think that, for finishers, it's more a question of how good your honing is in the first place and which hone you personally prefer (maybe the finish it gives, but also cutting speed, feedback, ease of lapping/refreshing, size, cost, etc).
