Some folks like the retro look.
If you look at tubes, consider the type of tube and the circuit.
Fat 8 pin tubes like the 6SN7 or 12SN7 provide natural tone, great musicality, but not the fastest or most detailed. Smaller 9 pin tubes like the 12AU7 or 12AX7 are more neutral but provide less tube bloom).
Can't recall which, but one of the Mapletree pre-amp reviews outlines the different sounds from CF, SRPP, and passive circuits.
Then there's the synergy between various tubes and circuits. And don't forget the wide variation of tube cost when it comes time for replacement or if you want to try rolling.
Many of the compromises in audio can be found in tube pre-amps.
