It all depends on your budget, how many miles you will do etc. Its not as simple as which it better

Normal driving, the valves act as a normal car, and a 1.8 in a vectra is a bit lethargic (I know as i have one) and this helps the economy, but boot it or go above about 4500 rpm and the valves change by either opening further or how they open changes giving it alot more poke but use more fuel.
