I found the Lemmy frontends to be all kinda crappy and lacking in options.
Alexandrite for example aligns its content to the far left side of the screen, which is super annoying on a widescreen monitor, which are like almost all desktop monitors nowadays. It also does not show any NSFW / 18+ marked thumbnails, just some hyperlink symbol. Thumbnails are also very small and do not fill out their available space in compact mode like they do on kbin / mbin.
