Triple X is carlube oil owned by chemical firm Terosyl they make oil for Asda, Tesco etc and also paint in aerosol cans, car shampoo and lots of other random cheap car items. I wouldn't put it in my car personally, not an oil brand snob, just conscious that its the only thing preventing metal to metal contact, and I want a good base oil and shear stability for as long as possible especially with turbo charged cars. Nothing fancy but most of the premium brand oils will give you this and possibly some piece of mind.
Comma is owned by Mobil which is Exxon Mobil and a subsidary, also Esso in the UK is owned by Mobil. Comma oil is pretty good and official partner to the FIA championship GP2, so while that doesn't make it the best it has considerable access to base oil and performance technology due to its parent company.
I have used it, and would do in the future.
Personally i don't like switching brands though, especially if a car is long running on one oil...
