If you want AE, you've got a few choices, Bessa, ZI, Hexar RF, or M7. If you want built-in meter, but not essentially AE, then that expands to include Leica M6, M5, and MP.
I used a ZI for a couple of years, cracking camera. Now, simply for a change I have an M6. The M6 is heavier, and feels more solid, whether it actually is, well, it's a matter for debate.
The M6 downsides are lower top shutter speed, which matters a little in very sunny places. The upside is more frame lines, the red dot (if that blows your skirt up), and maybe easier to get serviced.
The ZI though really is a brilliant camera, and it's hard to recommend against them.
I have only limited experience with Bessa cameras, but I like them, plus they are cheap enough compared to the M6 to get two, so you can get one with wide frame lines (R4A) and with normal (R2A), or with a 1:1 finder, (R3A).
