I think part of the reason why a lot of people (including me) like these miniatures, is that they are hard to get, so there is a collecters issue and the fact that they often just ooze atmosphere (something to do with the poses), something that I think was lacking for ages from ca 1990-2006. Nowadays seems to be a goldens age for not only clean crisp sculpts, but also for the look.
The collector in me still we like to have more of the old grenadier sets, but the painter in me more readily paints more of the newer miniatures...
