Since you haven't mentioned your priorities, judging solely by the fact that you are confused between the two, I'd say go for Oriel.
A turbo enthusiast looking for the X factor in acceleration would just go get Turbo, if both Oriel and Turbo are available at similar prices - which is the case these days.
For the vast majority however, petrol issues, engine deterioration, and resale matter a lot, and for them Oriel is a more practical option.
