YMMV - here in Munich I have experience with both e-scooters and the "leading" bicycle-sharing solution (MVG Rad). E-scooters are about 2x more expensive, but also considerably more reliable. With the bicycles I regularly have to call the support hotline because the bike won't unlock or the return doesn't work correctly, also on many bikes the gear-shift is partly broken, the saddle is adjusted wrong (not the height, which you can adjust yourself, but the angle, which can make longer rides very uncomfortable) etc. Some of these can be fixed with better maintenance or better design of the bikes, but others are due to scooters being technically simpler and easier to use (they already have a big battery that has to be charged anyway, so not unlocking because of low battery is less likely, plus they are regularly picked up, charged/serviced and then put back, which is much harder with a full-blown bicycle, they don't need a gear shift or a saddle etc.).
