The RebornOS-2021.02.06-x86_64.iso installer is the official one.
The RebornOS-LTS-2021.02.13-x86_64.iso installer is a modification of the official one with an LTS kernel, and it is to be used in those cases where the official one does not work. LTS kernels are usually more updated in their drivers by the manufacturers.
The RebornOS-MAC-2021.02.14-x86_64.iso installer has a Macbook kernel.
The installer with the LTS kernel was made so that LIVE starts with this kernel (the official version does not). This was done to help those who have problems with the official installer, as the LTS kernel is usually more up to date by hardware manufacturers.
