Which ones to move on?

So I've got the Trimui smart pro on route. But which to move on.

Currently I have

Powkiddy v10 Anbernic RG28XX Andernic RG 35XX SP Trimui Brick - sexy red.

My current thoughts are, the RG 28 and the V10.

I also have my 3DS and NDS lite both now open with Homebrew.

I play mainly GBA.
