I've been using ladders to get up and down, but water elevators seems like a cool way to get up and down. They work faster, and I don't need to keep pressing keys to get up or down..
But I have some flaws in my design.. First, I haven't found a way to not step on magma block. I tried to put magma block one block below exitpoint, but if I put in a trapdoor, fence post or anything like that, I disturb the water stream and it is no longer going fast downwards.. Is there a way to avoid hitting the magma block when at the bottom? Not like it's much damage to talk about, but would be nice to avoid.
Also, going down, I can get out at various points, though I have to be fast to get of at the right stop.. But going up I seem to go very fast and I'm not able to get off at an intermediate stop. If you want to stop at many levels, are water elevators still useful? Do you typically create elevators going only one level up at a time, so you need to switch elevator to go further up?
I prefer to use water elevators that are just waterflows with air columns on all four adjacent blocks (rook adjacent not queen adjacent so no diagonals).
This is slower but it allows you to breathe and increases your max swim speed especially before 1.13. No magma blocks required and no magma damage.
Otherwise, make layered elevators are you implied.

If you struggle to swim fast enough in 1.13+, you can have just 1-3 columns, so long as you lean into the air as you swim up. Prior to 1.13 you want all four columns because swimming worked differently then.
For now I created elevator within 7x7 structure, with an elevator in each corner. One going downwards, as I manage to get of at speed anywhere there.. One express up and two alternating upwards to interesting levels.. Might redo with more experience..
I read about the water above landing trick, but playing in a hardcore world it seems dangerous, if for instance a game patch should alter how it works or I should manage to land on sign holding up water or something.. Anyhow, bubbling down is more than fast enough for me.. Bigger gaps when getting off the upward streams sounds like a good idea..
