Both. I use a digital rig for my boomer classic rock cover band that plays wineries that have strict volume restrictions.
Then I have a tube rig for playing in my punk band.
When I've played bigger venues (and have people to help carry stuff) I go bigger with the tube rig - you only live once, right? Might as well do wet dry or stereo.
There's no question to me that tube rigs sound better for any live application, in any legitimate rock or metal setting. Digital rigs with power amps can sound good, certainly, but they have never sounded "holy shit" good.
(In before digital partisans tell me I didn't do x or I need to download patch y, or my power amp is wrong, blah blah blah excuses that are thinly veiled accusations of not being able to dial in a tone)
When you start hearing the keening lamentations of Karen's that the guitar is too loud during "la grange," that's where digital rigs are the answer. And they do that phenomenally well. They also can cover an exceptional amount of ground - for my cover band, I would need a pedalboard the size of mount Olympus and at least two tube amps, and THEN I would need to try to control my volume somehow after carrying a ridiculous amount of gear around.
