The figure kits from ICM can be sort of hit or miss; it sort of depends on the age of the kit. The older kits were sort of rough - I have a set of crew for a Panzer IV tucked into a box somewhere that I consider to be pure junk. Excessive sheets of flash around parts, poor sculpts, and issues with scale were all considerations when I decided to shelve the kit. To be fair, it was one of their earliest figure kits and it really showed.
But, like a lot of Eastern European manufacturers, ICM has gotten better over time. The newer releases are better engineered, better sculpted, and a lot closer to scale than their initial figure kits. Some of them are now included in Tamiya's kits as a bonus feature.
