Grouping similar tables is a nice feat. But the top100 will always been a totally unuseful and misleading list. People simply give top marks to their machines, especially the expensive ones. That's all about it. The valuable thing here are the reviews: read them and you can often perceive who is being honest and who is not, who is an expert and who is not, who has similar tastes to you, etc..
Everybody has different tastes, but if you want to know which ones are the top machines, speak in person with a collector or player with long experience.
