The new website is really great looking and modern. The old one was starting to come off as a little dated.
I do have some misgivings about the copy of the page, though. Particularly about the parts that discuss available software. For example the section listing desktop environments mentions only Budgie and Xfce. For someone, who has very little knowledge of Solus and treats the website's landing page as the primary source of information (reasonable assumption, I feel), this reads like those are the only options, which I think is not ideal. It'd be better to either mention all flavors or none at all, but with a link to a separate page listing all of them. The web browser part has similar problem singling out Firefox with no hint of available alternatives, making it look like that's the sole option. Not mentioning all the alternative office tools is ok, but people do have a tendency to feel strongly about their preferred browser.
I am also missing a compelling "sales pitch" that sets Solus apart from all other distros. Yes, it says it's "designed for everyone" and is "ready to go", but that isn't informative for a prospective user, as similarly hazy statements can be made about every general purpose distro out there. The rolling, but curated nature is one compelling reason to try it out, but is not apparent from the copy. "Install today, update forever" is again vague enough that it would hold true for both a cutting edge distro like Arch and an extremely slow moving one like Debian. Solus also offers excellent performance and gaming experience. That is actually mentioned. In a way. All the way down, just above the footer, in the gaming section, where only people checking Solus specifically for gaming would look. And even they will be left wondering what exactly "optimized gaming runtime" relates to. Steam, which was mentioned earlier in the sentence? The system itself? Does it make games run better or what does it actually do? Not clear.
What I'm getting at is that someone checking the landing page will be looking for a bird's eye view of Solus, but the way the copy is prepared is a little too generic and imprecise.
