Live Photos transfer just fine as long as you stay within the Photos environment. If you use iCloud Photos or AirDrop, for instance, the Live Photos go from Photos on a phone to Photos on the Mac, and they're just fine. If you are unable to do it, then you should work on correcting that. What do you think that you're doing wrong?
But for nearly 1 TB data it makes me really mad… to pay next hundreds $ for iCloud space
You must be falling for some scam is you're asked to pay hundreds of dollars for 1 TB. Apple doesn't offer a 1 TB plan, so this must be another company. You should look at the Apple site to see what's real.
This is terrible disappointment after a try to switch from Win systems.
I'm sorry. But I think if you spend as much time looking at how it works rather than ranting about how you don't know how it works, you could learn how it works.
You haven't even told us how you're attempting to transfer these pictures. Apparently it's not the right way. It's like you don't really want to know. If you can ask questions in a friendly and respectful way, without all the extraneous comments, then maybe we can help.
