I like it!
Going for a short bus? Looks like you've got everything tetrised in there pretty nicely!
When the kitchen shares a wall with the bathroom, your pipes don't have to run around the bus so much, localized water, it's handy methinks. But even so, if you have more space with the other layout, it's probably worth it. Space is a premium in busses!
With the second floorplan, the popup table by the bench would allow someone to sit on the corner of the bed, makes a little more sitting space?
One tip: Draw up some more floorplans, even if you're not really into the layout, draw it, play with it, you might find something you like better that you didn't consider before. I've drawn up like 20 floorplans. Ironically, I ended up with something similar to the first floorplans I did, but better lol
