A few years back I played an Ampeg SVT CL 300w valve head and 610 cab
I now play the Ashdown RM800 !!
Do I miss valve amps, not sure I do really and having a lightweight Class D head is a joy to carry around.
I think they do give you a warmth in the tone but in most band small / med sized gigs I don’t think you would hear a lot of difference in my opinion
