Well, yes to both, and more.
Let's put this way:
-- you can abuse it.
-- no clicks.
-- no springs on ballistic-punch effect
-- pilots are not articulated (most are not even painted)
-- cockpits are not detailed.
-- relatively alot lot cheaper than the DMZs.
-- have delicate parts that may easily break (tummy handle on the DMZ-01, especially)
-- nice paint and weathering details.
-- detailed cockpit
-- spring-loaded ballistic punch
-- lots of clicks
-- articulated Micro-Man pilots/figures.
-- can be quite expensive.
That said, DMZ-01 has alot of issues regarding fit and quality stuff since it was the first iteration. It can be a pain to handle. It does really live up to the junkyard-dog feature from the tv-show, fwiw.
Subsequent DMZs (starting with dmz-02) are all comparatively better in fit and quality stuff, and more enjoyable to handle than dmz-01.
Fwiw, I think the DMZ-01 is fine as it is despite the issues, but I personally wouldn't get a DMZ-01 for more than 8000y.
I think Jenius has an old written review for the DMZ line: http://anymoon.com/blog/?p=5915
However, I'm not sure if he has an actual yt-review for the various DMZ 'dogs, but he does have the DMZ Red Shoulder Custom Parts yt-video. Those RSC missile-parts require lots of Future polish to keep in place, btw.
Browse YT for other video-reviews to have a better gauge on 'em.
