You’re better off with a 50/100 watt amp with a good master volume than a 5 watt amp that needs to be cranked to sound good.
For a while I had the Victory Kraken head which you could run at 50, 25 or 1 watt and all you got out of the 1 watt setting was that it was still loud, it just now sounded awful.
Having said that everyone has said good things about the MT15 as mentioned above - I think it has a lot of the specs of a 50 watt amp (i.e. transformer) just running at 15.
edit: If ss amps are noisy I’m not sure tubes will help with that
