Thanks for all the info and advice, it's much appreciated.
I did wonder if some of the clothing (especially products not featured in the Daz shop) just sucked when it came to collision issues.I'm going to try and stick with costumes which the Daz shop has stocked and only bother with exceptional looking outfits from other vendors.
It's a hit and miss. Some clothes on Daz store work fine with that, others not, and the same is valid for other stores (and freebies). And the same goes for adding up a modifier.
As someone else pointed out, smoothing and collisions are different, but they are the same modifier.
Incidentally, it may be just bad luck for me and the props I used, but recently I had to open a ticket and had to interact with DAZ, with the latest version of Daz Studio, I had an effect in which even if the prop was not yet in contact with the character, the collision already deformed the character, leaving an empty space - in the end they suggested a work around, collision with an invisible prop, and put another visible instance of the prop closer, so it looks like the one closer is creating the effect), but it seems the problem was due to the high mesh of the G8 character, that somehow "amplifies" (my wording, not theirs) the effect.
I do not know if others have had a similar problems, in the previous version I remembered I did not have the problem - I am just saying in case you want to do collisions with props and have the problem.
