I don't use DA anymore, I don't think I'd ever come back to it anyway, however I think Eclipse was a step in the right direction. DA has always been a disgustingly outdated dinosaur of a website, and up until Eclipse made an appearance, the only reason the UI was easy to navigate was because most had been there too long to get used to anything else. Eclipse gave the site a much needed overhaul and breath of fresh air, and tbh I want them to keep updating the site to keep it looking fresh.
That being said, I do have several gripes with Eclipse, namely the poor optimization, in-your-face color schemes, and profile layouts. Eclipse runs like GTA V on a 2008 Dell computer, horrible. Even my PC, which, while outdated asf, can still run monstrously intensive games, hates navigating Eclipse. It's highly unfriendly to lower end devices and I kinda wish it was as seamless to navigate as most modern websites. Other sites that have had to overhaul themselves to a more modern state still manage to run very well even with animations and large images rivaling those of DA, so why couldn't they optimize?
Also, the color theme selection for eclipse suuuucks. The Green/Older is the most friendly on the eyes currently, with dark mode in second, but even dark mode has far too much contrast to be comfortable to navigate for a long time, the bright white text layered over near pitch-black backgrounds is awful on the eyes. For a site run by supposedly artists, they really could not take the time to reference other sites/services like discord that did dark mode right? Really? Light mode just, sucks, goodbye eyes, shit's a flashbang.
On that topic, profile customization sucks now, I mean, it already sucked before but it sucks even more now. Non-core profile directories? Gone, DA ID? Gone. But same shitty tiny little gallery preview that shows maybe 10 of your deviations at a time? Check! They really looked at the old site and were like, "MmmMmm people's profiles don't look similar enough to each other, let's fix that!" Then took 5 steps back. Pretty annoying. I don't blame people for wanting the old site back, even though I don't feel the same way, considering DA managed to mishandle eclipse that badly, I do hope they fix it up before switching over completely, Eclipse could be great if DA listened a bit more.
