I love Tango In the Night
It's my second favorite Mac's album after Tusk. "Little Lies" is horrible, but the rest is really impressive. I strongly disagree with you about the production, though. To my ears Buckingham used Fairlight CMI in a pretty inventive way, unlike anything else I've heard in pop music. He definitely got more interesting textures and sounds out of it than, let's say, Peter Gabriel on "Security" (the shimmering sounds on "Everywhere" that clearly imitate African thumb pianos, voices on "Welcome to the Room... Sara", the backing vocals effect on "You And Me"). TItN has also aged really well in hindsight (there are tons of new bands around that practically try to copy Buckingham's approach on it, Chvrches come to mind immediately).
I'm really dumbfounded why you'd compare the production with Skylarking. Skylarking is practically a retro album on which Rundgren tried really really hard to imitate the 60's psychedelic records. There is more echo on Skylarking than anything. Apart from that, it's more 'arrangements' than 'production', i.e. strings, acoustic guitars, etc. It does have a lot of drums that you can broadly categorize as "80's drums" and technically compare them with drum sounds on TItN. But while Rundgren's are all booming and loud and generally really really really 80's, Buckingham's are thin, mercurial and infinitely more subtle. I don't get "half the brains" comment at all.
