X220 vs T450

I just got an X220 from ebay (for some reason coreboot is not working properly for this computer), I also have a T450 which works pretty good but I cannot install a wifi card (only an external adapter) and a T400s but not so powerful. Which computer should I keep for day to day computing?
It's a shame I cannot install libreboot or coreboot on the X220
T450 has Boot Guard. It's impossible to replace the UEFI firmware. And this renders it also impossible to remove the white list restrictions for WLAN cards. Stay away from it.
