Tablet. Convertible is the “worst case” alternative.
→ F41 Change Proposal: KDE Plasma Mobile Spin and Fedora Kinoite Mobile (Self-Contained)
I trust these maintainers to put appropriate efforts in this, and in the meantime, the alternatives are acceptable as long as they are stable, which is less an issue in terms of the GUI but more one of drivers and hardware compatibility of existing devices. The major issues are imho 5g hardware with drivers in the vanilla kernel (the kernel supports several, but not all 5g adapters used in current devices), and support of the ARM SoC of tablets. The latter is a tablet issue, the first a general issue we currently face in 5g, partly still 4g. The two obviously complement each other in a negative way when it comes to tablets as most tablets with 5g have ARM, not intel/amd.
Be careful with generalizations. Not everyone switches to a tablet for the same reasons and with the same intentions/expectations/needs. Also, you could focus on a slightly less cursing formulation in here
