Both are non-abbrasive so will not help remove fine scratches but fill them with the oils, temporary adn will wash away after a wash or two. If you want to remove scratches you will need an abrasive polish or if very fine something like BF Gloss Enhancing Polish which is a very very fine abbrasive polish (Little lower or like 85rd) On how they work, I have not used Lusso but will say SV CF is a dream to use, very easy on and off and really deepends and crates a rich surface for your wax.
As agpatel said, neither will remove scratches or swirls. They are pre-wax cleansers, and will clean the surface before you add a sealant or a wax. If you want a very nice polish, have a look at Menzerna PO85RD. It cannot be beat.
yep neither have decent swirl fillers imo, and Lusso didnt look to fill at all in my experience, in fact some swirls re-appeared because it cleaned so well if you want a swirl filling paint cleaner try Prima Amigo or Blackfire Gloss Enhancing Polish if you want a correcting paint cleaner try Optimum Poli-Seal or Dodo Lime Prime (not Lime Prime Lite)
I really do not like Lusso Revitalizing Creme at all and am now on my 3rd bottle. It worked beautifully the first time I used it and was extremely impressed with it. However, I used it again on my black Saab and it marred the crap out of my perfect paint. I thought I had a contaminant in my foam applicator pad so I threw it away and got a brand new applicator pad. I tried a new panel and it marred the crap out of it too. I poured 1/2 of it out to get to completely fresh Revitalising Creme and with a new applicator, it marred again. I got two new bottles and they all did the same so I don't know what the heck happened.
christian lusso rc isnt a good product regardless there are far better options out there, i def would move onto something else if you want a good cleaner (only) than doesnt leave anything behind, try the dodo lime prime lite or cg vertua-bond
