It's very regional.

Buses meant for right-hand drive markets like the UK, Australia and Japan are (with very few exceptions) shaky, low-entry configuration two door junk, or double-decker one door junk.

If that's what you're used to, even the most rickety light rail system will feel luxurious by comparison.

Left-hand drive low-floor buses with three doors, and articulated models with four doors, which are intended for the European market, are as a general rule much more comfortable. If the buses you normally take fit the latter description, you'll probably find the average tram worse.
