What kind of question is this? Sell the Framework and use the money for maintenance of T480. Buy new batteries (Lenovo original if you can find a source) and dual-pipe heatsink (if your unit is missing the Nvidia gpu). Clean the dust and with compressed air and replace the thermal paste.
That T480 will serve you eternally. Especially with Linux. If someone is able to port Coreboot with Coreboot configurator into that model, donate some coffee money for the devs.
What are you even asking? There's literally zero reasons you to force you to prefer Framework to T480. And some other might prefer Macbook over anything etc. The personal preferences aren't a reason to force or argue.
