I wouldn't say that as I think Fastboot3DS is much better than boot9strap though to be fair fastboot is just a different implementation of the same underlying mod.
fastboot3ds is a complete replacement of the 3ds 2nd stage bootloader, firm0, ( booted after bootrom)
b9s is a bootrom exploit, that allows us to effectively fake sign code
ntrboot is an undocumented feature of the 3ds, used by Nintendo to more than likely to install OFW to factory units, and for repairing systems sent to them, b9s and ntrboot were discovered after the 3ds bootrom was dumped
