I only do steel so didnt need ac. The digital-ness is nice, especially for the framebuilding. Often i'm fiddling with the amperage, mid welding. Its really nice to be able to control the amperage +/- 5 amps and not wonder how much you're changing it. I only bought the digital because it was on sale at the time, but it is very worth it.
I really like it, The only small thing i dont like is sometimes the high freq start isnt massively consistent at low amps. But its not a major issue, and is a given with lower cost machines.
My one is the digital dc one. This one
