Based from what I have read..
Tama' Iron Cobra's are indeed the sturdiest pedal around within its pedal class. They are really built for heavy hitters and road abuse..only downside is between the available pedal model options, if you do not know what suits you best you would have to experiment..unlike the Pearl Eliminators where you do get all the options of IC's in one package though interchangeable cams. As some people find the IC's a bit heavy and not suitable for light bass situations (specially the power glide which is intended to accelerate speed and pressure as the beater reaches the bass drum head). But then again a lot of people swear by the IC's because it suits their need flawlessly in their type of music which require hard heavy hits. But still I have seen some people play jazz with the IC's with no problem at all..
Next in line in durability is the Pearl Eliminators..the debate between which one to get has been talked about repeatedly and endlessly. Don't get it wrong, Pearl Eliminator's are very sturdy and outstanding pedals but TAMA IC's just took the extra walk and added more on durability. As with drumming the usual concept we fall down with is preference and for which type of music it is to be intended for use.
Imho..Pearl and Tama are equal in rank for both has its strength's and some what shortcomings..but for people who are unsure of what to get the Eliminators seems to be a safer and more practical choice to take. If we only had actual testing opportunities like in the US for potential buyers to make a better judgment on which to get these matters would be addressed properly..
