Priiloader is worthless compared to BootMii.
Priiloader is worth it though, you can unbrick your wii if you forgeted up, and you can make your own custom wii boot screen, and load files from there without going to the system menu.
My Wii is Hardmoded, Black system menu, custom boot, play DvD's, gba, snes,ps1 emulators installed, a working youtube browser(wiimc), riivolution is the best thing ever too, and there is other crap I did too, Hardware wise I uninstalled my wii's gamecube ports, and replaced it with a control module for the led's the wii has installed, I replaced the blue led's with red ones, got a black wii shell, cut some areas on it so that it has red light bleeding off it, and maybe I'll install a something else soon considering I still have room on the gamecube controller ports.
I am never selling this wii.
