Fig8 can get quite hard to untie after several falls but you're right, it generally isn't too bad after one or two small falls. Bowline is however trivially easy to untie in the same situation.
I have managed to tie one I had to cut out but I'd been towing a car on it
> Reading all this through, simply to add to my knowledge is not a good enough rationale for me - as I've previously stated, I don't find knot tying an easy thing to learn and I'm concerned that I would mess it up and not be able to easily tell.
To be brutally honest, if you do any outdoor climbing that is the main reason to learn it and it's a compelling one, it's a genuinely useful knot that's often the best solution to a problem.
They're not actually hard to tie and if you get it wrong it just falls apart in your hands so you try again, when it's right it's obvious mostly because it's so simple.
Tie one (without a stopper) then have a good look at it for a couple of minutes while you poke and pull at it. Once you understand how it works (again, it's gloriously simple) it becomes easy to check it's tied correctly and there are no tricks (Rabbits, trick twists etc) needed.
There's no reason to to at least try to learn it, so long as you stopper it it's nearly impossible to make an unsafe one.
