Good post.
Imo the dc HT IM figures are better overall than the plastic predecessors, as HT has added articulation to them that allows you more pose options that the plastic ones can't achieve. That is the major selling point to me.
The weight of the dc figure in hand does add a sense of quality to the purchase which is always a plus b/c let's be honest - who wants to feel like they got a cheap pos?
The plastic ones do not feel cheap to me, but many others in the past have posted they feel the plastic is cheap in hand so it's important to understand that opinion and just accept it, not try to talk them out of it.
In the end, the margin of how much better the dc figure is over the plastic figures overall just isn't large enough to make me happy with the price hikes that HT has been employing at this time. If I have a choice of paying $250 for a plastic fig or $350+ for a dc figure I'm taking the plastic figure in the long run.
