Yes, definitely keeping it, gigged it yesterday and it sounded great. I really like the stock speaker actually, although it doesn't like being cranked and gets harsh and flabby when it's too loud. Saying that it will do just well for now.
Just used a Tonerider American for some grit and looks like the perfect small gig / practise amp.
Lots of guys in the US seem to upgrade the OT but I think part of the charm of a small amp is that they do lose a bit of control when cranked.
