All the Blackstar, Maxon, Fryette and AMT tube pedals look really cool. I tried a couple of the Blackstars and liked them a lot, but ultimately felt like they were low on features for the price.
I also like Soundblox because they're such great pedals, but always with that utilitarian ugly duckling factor that says 'fuck your silly graphics this is serious shit', somewhere between Eventide and Boss. Old Soundblox are big box classics all the way now.
TC Nova series is another good example of high quality with purely utilitarian looks and no decoration. And of course there's always rack world.
I still like some nice graphics, but it hasn't been a purchasing factor for me for a long time, and I don't really have anything cool looking like that anymore. I like the way my Swollen Pickle looks and don't need a sexier muff.
I tend to go for the stuff that looks more like manly tools and futuristic gizmos now that I'm older, but I used to be more into the artistic aesthetics, which I still respect and appreciate. The last pedal I was tempted to get just for the graphics (it's still not beneath me) was the Devi Ever ZG, because I adored the longcat graphic.
I did this with a vintage MXR D+..... which now doesn't work. There's a reason why they put circuits in fully enclosed boxes. I suppose you could just partially attach the bottom plate. Still not ideal if the power cable get pinched each time you step/press on the pedal.
