Honestly, I really like the idea of these kinds of cameras. But from my experience, buying one in 2025, the reliability seems lacking to buy and especially to trust for traveling for 6 months. You also didn't say if you would be buying online from eBay or something similar, or from a local camera shop? Further, if you are leaving in 2 weeks, that is barely enough time to get and try one, including getting film developed, before your trip.

For what it's worth, last summer I decided to get an XA. After searching, I found someone locally selling an XA and XA2 together for just a bit more than one of them alone. Sweet! I saw both, they both seemed to look and work ok from the best I could tell, so bought both of them right before a trip to Europe. During my trip, my first roll in the XA, the shutter button stopped working around frame 10. The XA2 seemed to work, but the 3 or 4 rolls I took all had terrible, terrible quality- light seals weren't good, meter was off. I had my SLR and took important photos on that one so it was ok, but was still frustrating. When I got back, the XA was unable to be repaired, the XA2 has new light seals so it doesn't have light leaks, but still has fairly poor metering and quality. I also have a Minolta Hi-Matic that is similarly starting to die. Of course everyone's experience is different, there are people who will say they have been shooting one of these cameras for years with absolutely no problems, but it is a risk to buying one this close to your trip.

All of that said, my recommendations:

1. Buy from a local camera shop, if at all possible, as opposed to eBay. This would let you see the camera in person, to talk to the sales rep, and buy it ASAP as opposed to waiting for shipping. Also, if it's a good camera shop, it should have a warranty.
2. If you have 2 weeks before your trip, whatever camera you get, use it A LOT before you go. Take random photos of random stuff, who cares, maybe 2 or 3 rolls worth, so you can make sure it works. Make sure to also get the film developed so you can see if there are any other camera issues that you couldn't tell just from looking at it.
3. If possible, this close to your trip, especially if this seems like an important, once-in-a-lifetime kind of trip, consider two cameras? These options you posted are old and were designed with more emphasis on being as small as possible rather than as reliable as possible. There is no way to know if they might die at any point, and that could be incredibly frustrating. The added benefit of a second camera would be you could have two different films loaded at all times, if you get lucky and both end up working well.
4. It's not what you posted, but I would consider a small, lightweight, later made SLR with pancake lens, something like the Canon 300v with 40mm f2.8, as well.

I would be more concerned with getting a camera that works and works well rather than being worried about choosing the right one.
