The bike I started on again after my hip replacements is a Jamis Citizen 1 step-through. It has a 48-38-28 and a 14-34. But what is interesting is the spacing of the rear cogs - 14-16-18-20-22-24-34 - six 2T steps, then a 10T step to the granny gear. I really like that setup - I like the close ratios most of the time, but that 10T jump to the last cog (which shifts just fine, btw) can be a real leg saver!
Now I've kinda gone crazy with gearing options on my old racing bike. I have 5,6,7 and 8-speed wheels, some I haven't even tried yet. Currently it has a 46-42 and a 6-speed 14-28 on the rear. That is enough to get me up some of the hills around here, but not the steep ones (I'm old...), so I have an alternate setup with a 48-38-28 crank, wider range derailleurs, and an 11-34 cassette to try soon.
It's funny how the old "macho" thing about big chainrings and small clusters still affects my thinking. I have some clusters I bought that I'll probably never use. Oh, well!
