My friends. I think this topic will explode soon
Cmowla,it´s hard to name the "best" mp gamers. Sure you can name like 20 players that are for sure one of the best economy mp players. However there are many aspects.
Like Sado said Spamming is not everything. You also need to use them wisely. There is also a difference in gametime. Some players might win most games with rushing the other team with some horses (2vs2 for example). This fact doesn´t make them to very good players. However if you think about your strategy in every game and you´re trying to do new things, this shows already that you are little bit of "skilled".
Also note that there are different gamemodes. If one player lost nearly all 1vs1 vs other players, that doesn´t mean that he will be a bad player in a 4vs4. I guess you mean 60 Min PT Games with x1/x1 Speed, because I´m pretty sure that those "Pro players" have a nearly perfect strategy for their economy, so it works best as possible in 60 Min PT. If these players start play 90 Min PT Instead, they would need some time to improve their economy. Sado just listed a random lists of players that are playing really often, but it has nothing to do with their actual skills.
Also a skilled players isn´t someone who has 50 prebuilds on his pc saved and plays Richland, GoldenCliffs,Across the Desert all the time and is good on these maps. There are even players playing all the time on one location and don´t want to test another one. A good player is someone who could also make a decent army on a map that he has played once (without watching the mapeditor (even while the game is running) for 20 min

)
About Tiank. Well when I had a "good time" I never had great armies, but still I had in many of the (3vs3/4vs4) games most killed units just by the micro feature. So this could be also your advantage in your "first games" cmowla

. On the other side you can be the best micro-man on the world, but if you have a really bad army and a "pro player" rushes you with his big army, you have no chance, even when you us your whole brain and can micro best on the earth
To the discussion about micro and macro. Well, if the enemy attacks you or your teammate in an economy map you have to react as fast as possible. You have to thing what the enemey could have behind the fog of war in a few seconds. Then you have to micro your troops, go back, or fight. With this feature alone you won´t win a single game, you really need to communicate with your team. Even if you haven´t a microphone and you are not writing in a chat, you have to ping somewhere, so your allies are warned.
So to your main question

Join Teamspeak, I guess there are still some active KaMPlayers that are playing this game online like every day

You can ask them to watch a game, you can skip the Peacetime, if you wanna see first what armies they will have and how the "NOT-AI" players are fighting
To your point, to name some good players: Best way to find best players, is to see how they play in a tournamnet for example. However there aren´t many economy tournaments where all players from ts played and really no tournament, that didn´t fail XDD
There are also some lists of "the best players", but I don´t think they were actualy serious at any time
If you don´t want to watch livegames, like you mentioned with your replays, the best would be also if you join the teamspeak servers and watch there for Replays in the downloadarchive.
This is the biggest Topic in this forum that have replays from good players:
viewtopic.php?f=25&t=832
However the first Posts are already 3 years old, so it isn´t worth to download them, because you would have to download an old remake version AND the balance of the game has changed massively (Market/armybalance/Cornbalance..)
