Has anyone used both of these options, and can give me pros cons to them?
Thanks,

Actually that is a good start. I just didn't want to purchase the UA for example, and then find out that the Mk0 is light years better as far as wicking moisture. Do you find you feel warmer in one over the other? How do you like the jumpsuit like the Mk0 vs the two piece upper and lower under armour?

The MK0 probably wicks better. One thing about the MK0 is that after a day of diving it get a nasty smell from the perspiration. Almost like sour milk, so keep it washed. I wear the MK0 when our water reaches 65-70 and am perfectly comfortable. The one piece suit keeps me covered without having a separation between the shirt and pants. Generally the only time I wear the under armour is when the water gets below 40 degrees as an extra layer under my MK2. That is enough for me to keep warm in cold water.
If I had to pick I guess I would go with the MK0, but since I already had under armour I like it when it gets really cold.

Is moisture wicking really that important in a sealed system. Sweat has nowhere to evaporate in a drysuit. If I am misunderstanding something please let me know but it seems to me that any persperation "wicked" by the undergarment remains trapped in the suit.
Am I missing something?

It can make a BIG difference on a very cold dive. You're right that the moisture is trapped, but if it is left against your skin by undergarments that stay damp, you end up extremely cold.
Picture going outside for a long hike in February, except your sweater under your winter jacket starts off damp. You won't be happy after a while.

I went with the Fourth Elements - the Xerotherm base and the Arctic heavy layer.
Wicking is very important - if you get a slight leak, it takes the water away from the skin so you won't be chilled. That is why everyone says to not have a cotton underlayer.
Jumpsuit versus two-piece -- women know this answer. You gotta go poop . . . and you have to get totally nekkid to do so . . . Not too cool if it's cold and blustery!
Back to Fourth Elements - I was wearing the Xerotherm base vest and Arctic shirt - I left my drysuit open a half-inch or so (Fusion, so it's at the shoulder). When I went under, I felt that lovely chill start at my shoulder and spread. Fortunately, I could stand up immediately. The wicking ability of the Fourth Elements removed the water from my skin PDQ. Coming out, I was able to wring a cup or so of water out of my sleeve. Yet, I never felt chilled.
Good luck on your choices!
