Any technical reason why need to reinstall mx linux when there is a new version? I tried different distros before and I never heared of this.
You only have to do a fresh installation of newer versions of MX when the underlying version of Debian Stable that it's based on is updated as it was in November of this year (Debian Buster.) Otherwise pretty much all of the version updates will happen automatically through the regular update method as they were from MX-17 to MX-18, both of which were based on Debian Stretch which was the previous version of Debian Stable. Long story short: as long as the base version of Debian hasn't changed you usually don't need to reinstall MX to update its version. That's why some people call MX a "semi-rolling release."
Editing to add that even if a newer version of MX is released there's no reason why you have to install it. MX-18.3 will be supported at least until the end of 2022, and even older versions of MX are still supported. The main thing is whether or not Debian is still supporting their version that that MX version is based on: still providing security updates and bug fixes. Even when that stops, MX's developers are known for going above and beyond the call of duty to continue to offer support for older MX versions as much as they can.
But since you're talking about doing a fresh installation anyway, whether to Mint LMDE, MX or (possibly) antiX, why are you even worrying about it and about possible loss of data? You would install MX the same way you would any other Linux distro: back up your data first, install the distro, then restore your data. The entire process takes perhaps an hour or two depending on the speed of your back-up media and the amount of data that you have. As has been pointed out earlier in this thread you should be making regular backups anyway.
Regarding the question in the subject, I chose MX because it was the best compromise between performance on my ~10 year old PC that I had at the time and ease of use, because almost all apps that I wanted were preinstalled for me as though the distro had been custom-built just for me, because when I tested it everything just worked, and because 90% of the questions or issues I had (and there were very few of those) had already been covered in the manual, the wiki or the forum and were found by simply searching those resources, or by simply looking around in the OS and getting familiar with it, such as the MX tools which provide easy ways of adjusting configuration settings and getting MX to work the way I prefer.
