Revolutions is stronger than The History of Rome which I stopped listening to once I realised how many errors I could regularly spot just on the basis of taking a couple of undergraduate papers.
However, the Revolutions podcast is best listened to in the spirit of 'this is like the first history book you read on the subject when you're a teenager'- you know, the great 1970s or 1950s volume that's wound up in the school library. It gets you hooked, so you read more- and discover that that first book really left a lot of stuff out.
It's not so much that there's a lot of stuff that's wrong, per se, it's just that the interpretation does tend to be old fashioned.
But I like it, it does get better as the series goes along and it is miles above Dan Carlin's stuff.
