I have to disagree. I used the Apple IIe and the TRS-80 extensively during this period. I coded games and other software in BASIC and assembly on both machines. I poured over the schematics of both machines for hours at a time. You could literally say that I knew those machines inside and out.
What you refer to as "user experience" was not at all uncommon. The TRS-80, the Sinclair, and many other computers shipped in plastic boxes. I don't recall the Apple natively supporting a hookup to a TV (the TRS-80 did not), but this was certainly not a positive at the time... TVs were far more difficult to read and work on than monitors.
Both the TRS-80 and the Apple shipped with BASIC and connected to a cassette recorder.
There were dozens of other computers, but there were just a few that were commonly used.
The TRS-80 didn't have color and, unless you went into 32x16 mode, text would be unreadable on a TV (it had a matching TTL monochrome monitor built with a TV-grade CRT). 40x24 text was readable on the Apple II even through an RF modulator. While it didn't come with an RF modulator built-in, you could buy one cheaply.
In 77, there were more or less two computers that didn't look too much like office equipment: the II and the TRS-80 model 1. You mention the IIe and the Sinclair. The ZX-80 wasn't launched until 3 years after the original II. The IIe was introduced in 1983 (that is, after the III). The TRS-80 you remember is, most likely, the model III.
True, I thought I mentioned the color thing, but I guess not. You definitely could not read a TRS-80 clearly on a TV. You could on an Apple, but who would? Most people - remember the buyers were predominantly hobbyists and schools - bought the monitors.
I was working on a TRS-80 Model I in the late 70s, I want to say 1977 but maybe it was '78. I remember it vividly, even down to the massive 4kb memory expansion (which weighed around 10lbs and threw off massive amounts of heat).
Later on we got a Model III. It didn't have nearly as much character as the I. I didn't like the monolithic looks of it much but it was admittedly a much cleaner machine with the built-in disk drives (the Model I eventually supported 5 1/4" floppies but they were humongous standalone units.)
