Aloha! Back in my younger days I used to spend quite a bit of time in the Makaha area.
For a temporary machine, I would just grab which one felt best to me. We each have personal likes and dislikes and some machines just are a better fit for whatever little reasons.
I have a vintage Pfaff that belonged to a friend's grandmother and I'm a fan of them.
Some people don't like Bernina because you typically have to buy all new feet for each machine. Again, that is probably not a concern for you. My modern Bernina 820 (the computerized model) needs to go into the shop and so I've been using my portable very low end Brother because working beats not working!
