The motorola phones are neat, especially razr's, but practically disposable with their dismal update support lasting in some cases only a year or a major version I'd read. Selling me a $1500usd flip phone that is practically disposable oob for updates is a non-starter.
Now put GrapheneOS on it with better support than the vendor can provide, now that's highly appealing. I wanted to get a used pixel 9 pro xl to update my old pro 6 and run graphene on, but pixel 9xl have defective screens on whole, so maybe not, and with Graphene divesting from pixel hardware now, maybe this is the way.
grapheneos has a hard requirement for the vendor to provide software support for 6+ years (iirc), so i expect the updates will be better even for stock users
however this might be only for their new Motorola Signature line of flagships...
