That depends on where you are financially..or what you think is the better choice..... The buzz of an economic motor is a great thing to hear..Gotta love the sound and power, but sometimes the economy of it overrules.
I'm certainly not an environmentalist, but mpg in the 40's or higher is sweeter than the rumble of my American made V8.
But the throaty high rpm roar of an engine with tight air fuel ratios, screaming in chaotic harmony.. Be it regular gas, or the hair raising alcohol setups..... It always brings a smile to a person's face.. Every time I think of the sound.. I can smell the smell....
