I havent used softcups, but I read here, that they do have a sharp edge.
All the other Cups can be used over and over again. They last up to 10 years. There was somewhere the post of a woman, that she used the Softcps more than once, but I still think in the end you will spend more money on them.
I think you use the softcups not that long, because the are made of a different material. Except for the Keeper the others are made of silione where baktereas (?) can't grow.
The cups can be cleaned unter cold water. Some spots maybe need a litte rubbing with an old toothbrush or "watte". You can put it in your dishwasher if you want too.

Anfter the period you put it a bit in hot water and it is as new.
If you don't have a very heavy flow, you will hardly ever come into the situation where you have to change the cups outside of your home. Most here only change them in the morning and in the evening.
But even when, you yust wash your hands good, use wet papers, which you can take with you, or just use the dry paper and put it back.
It looks big? It is not that big and most women don't feel it once its at the right place.
Inserting needes practice. But after two periods you should be able to do it rather quick.
