Looking for a pocketable one-hand gaming device

As a sad former owner of a Miyoo A30 (screen died for unknown reasons) who really enjoyed having that little thing in my pocket and playing some one handed GBA games, what should be my replacement for it? I've narrowed it down to the following:

  1. TrimUI Brick: Seems to be getting very positive reviews around here. The only thing I'm concerned here is the controls. I love my TSP, but absolutely hate the microswitch face buttons and triggers (if that thing had rubber membrane buttons I'd probably never touch any other device). Does the Brick use the same buttons as the TSP? Also no stick here, so I can't play N64 on this. Not a deal breaker, but still a negative.
  2. Miyoo Flip: Lots of people seem to like this device, but with Miyoo's track record of screwing up their initial releases, maybe wait 6~9 months for better iterations and CFW? And how good is this device for playing one-handed?
  3. New MagicX Mini: Apparently they're coming out with a new MagicX XU Mini in a few weeks, running an Allwinner chip this time. Their last go, aside from the chipset controversy, seems to have been quite good. Should I wait for their follow up?
  4. A30: Just replacing the old flame, probably in red and gold this time (had the black one last time). I quite liked this thing when I had it, and it also worked as a thing to keep my kids occupied while waiting for the doctors or something like that. This is also the cheapest device on this list, so if the other three aren't significant upgrades I'm quite happy giving it another go.

Here's some devices that I already considered and eliminated.

  • Miyoo Mini/+: Seems to be completely outclassed by the Brick.
  • TrimUI Smart: Seems to be outclassed by the A30 and MagicX Mini.
  • Any Anbernic XX devices: All outclassed by one of the top 4 in every form factor.
  • R36S: Doesn't seem very one-handable or pocketable.

What are your opinions for which one I should go for? Is there a device I missed? Is there an upcoming device that I should wait for? Thanks in advance for the input.
