no experience with that particular model but I bought the 6852 black jungle (cheaper than the milspec) and you get what you pay for.
I used it for some jungle trekking in Panama and they worked as expected: good traction on the red clay, drain fast, mostly comfortable, not too heavy.
Next time I would get the milspec one as the leather is more durable, has more material so it is easier to put on and take off (the cheaper ones are a bit tight) and has more eyelets for the lacing - better construction overall.
chimo,
