It’s not about “today”, it’s about Linux vs Win/Mac. The former is a lot less consistent than the latter and this was just as true in 1995 as it is today.
At least with respect to Linux and Windows, both suffer from similar problems with consistency. Both have suffered from a great deal of churn over the years. Both have a variety of toolkits that vary in both appearance and functionality. If you compare current software on both platforms, it is difficult to claim that one is much better than the other. (Though I will agree that Linux was incredibly inconsistent in 1995.)
