You lose the ability to bypass the locked bootloader. Without that, you can't flash custom recovery.
If you upgrade, the best you can do is to use Safestrap, which only supports some ROMs.
If you want 4.3, stay on MDK and use one of the ROMs based on 4.3. You won't get the SELinux and Knox lockdowns.
My Android devices:
vzw Samsung Galaxy S4 stock MJ7, now rooted!
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
