Definitely Movavi is better than Filmora. I used (or rather, suffered from) Filmora for more than a year, and I can say that it is simply an inexhaustible source of bugs. Errors and crashes when using Filmora happen after every second action - when overlaying text, saving the finished video, even with banal cropping. By the way, my PC is not a pumpkin at all - Ryzen 5 2600, RX 580, 32 GB of RAM, so the problem here is definitely in the software.
But Movavi works perfectly - no glitches at all. Their functionality and price are practically the same, but Movavi’s interface is much more convenient, and there are no bugs.
