I never got the hang of TG2 so can't compare.

BUT to get your clouds down low in Vue you just need to go to the atmo tab and bring down the altitude - you can lower it to zero if you need to.  Then adjust the cloud height and height variations, cover and density till you get what you want.  Don't forget, you can have more than one layer of clouds.....
I think geekatplay have several tutorials covering this if it's any help.
