Looking at the newest Bentley, page 34.1a has late waterboxer 4 speed gear ratios and 34.1b has diesel 5 speed ratios listed.

Your question about first gear is valid but the answer is that the 5 speed was originally designed for the weak 1.6 diesel. Later in other markets it was fitted to models with more powerful engines and different ratios were used in some of those. North America only got the 5 speed in the rare 83+ diesel models. Other markets had it available in everything from that time on. The discussion so far has ignored differences in r+p ratios and that is very important to understanding driving comparisons.

I have Vanagons with both 4 and 5 speeds. The 4 speeds are much less cumbersome to drive though I would no doubt get past that point some if I only drove 5 speeds. 1st gear is positioned in a somewhat awkward spot for someone used to the 4 speed shift pattern. 1st is low enough that starting off in 2nd is reasonable on level ground. All 5 gears are closer together than the 4 speeds and top gear is nearly the same overall.

For completeness let me add that there were 3 waterboxer 4 speed trannys used in North America but all had essentially the same gearing with subtle changes. The ratios of each appear in various places in the Bentley. The Syncro tranny is a special version of the 5 speed with a super low 1st that is seldom used while 2-5 match 1-4 on the 4 speeds.
