I'm surprised you didn't get a sample from them. Sometimes, it seems like they're in business just to send samples. Every order I place with them has at least two sample items, and sometimes three at their discretion, which I think is a nice bonus.
To answer your question, the Supreme Lites are a pretty solid diaper. They're thinner than the Supremes but they don't seem to lose that much capacity. I decided against them for my day to day wear when I was 24/7 only because they were a little more than I really needed and some slightly cheaper/thinner options would do better for me. If I were more inclined to use over time rather than hold, they'd probably win out for me. I don't use clothlike covered diapers if I can help it, so I can't speak to those but I imagine they'd be the same other than the covering.
