honestly - I think that possession of a "personality" can be an asset or a liability.
When I was taking photo's for a living, the last thing I actually wanted from a camera was "personality" - all I wanted was a 100% reliable, solid, functional and unfailingly accurate in its execution tool to do a job. I don't want personality in a Hammer, or a Saw, or a Spanner either. I just want it to be plain, boring, and work exactly how it should.
My first SLR was a praktika - MTL1000 iirc, and a friday afternoon after a Vodka Lunch one at that. It was all quirks, and foibles, and a pain in the fundament, because no matter what you did, every 2-3 films it'd end up shredding the roll, and you'd be opening the camera in a dark bag, and trying to rescue the film shards. Yeah - way too much personality that one.
Replaced with a Canon A1. More like it. Worked well, was solid (from new - I know they ended up with the dreaded canon-cough as they aged, but I'm talking a from new purchase) and reliable and yes, it was in my eyes really nice to look at as well as handling pretty well. Main issue was for my "meat hooks" of hands, it was a bit small - but, as I wasn't really a photographer at the time, I was a walker/climber that took lots of photo's the trade off in size and weight was worthwhile.
Then I began assisting shooting weddings - and - also shooting fairly early "reportage" second reel stuff - The Canon A1 was good, but I was feeling the itch for Auto-focus for the "grabbed moments" - so - I traded the A1 and lenses in for a EOS-1 based system. This was IT this was the tool-camera i'd been looking for all my working 'tog life. Was quickly accompanied by an EOS-3 body because I got a good deal on one that was barely used - multiple bodies back then were often for "1 colour, the other B&W" - this combo saw me through to the end of any professional work I did. Sold the Bodies and Lenses at that point and had a hiatus of maybe 10 years of just taking photos when I went walking, whcih was covered with a procession of Canon Ixus point and shoot cameras taking me from film to digital.
Maybe 16 years ago, I decided that I missed having proper control over my camera, and had a few bob spare, so dipped back into photography, buying a EOS450 digital camera. I joined this forum, Photography actually became my Hobby - and, because I'd a fair bit of expertise from the film era, I started participating in the film and conventional bit of the forum. A wave of nostalgia, coupled with the (then) pocket money costs of the old film cameras saw me buying, refurbishing and using film cameras again - but - here's the thing - I wasn't searching for efficiency in these purchases - I was looking for things that WERE quirky, and that would make me think and work with, or around, their issues. Because, nailing the image wasn't the be-all and end-all - i'd got the digital eos for that - I wanted the old film camera for it's personality.
At the moment, I don't shoot anywhere near as much as I used to - day job, no money, and no reliable transport means I don't get to just disappear to the hills every weekend, so I'm back with digital and making sure I nail the image I want, because there might not be a chance of a re-shoot for years... Honestly, my film cameras really aught to get a quick run through, pass a film through them to prove they work, and get them sold onto someone who WILL use them and enjoy them - but - its a lot harder to sell cameras that have a personality
TL-DR - As a Pro, didn't want Personality in a camera, As a Hobby-Tog, Personality in a camera was pretty much everything.
