It looks like you are leaning toward the GTO, but I'll throw in my worthless half-cent anyway
I will start by saying I have never driven the Lancer Evo, so I cannot give a direct comparison. However, anyone who has driven a GTO and a Lancer are going to have some sort of opinion one way or the other, most likely based off of their drivetrain preference. These two cars, though both performance vehicles, are of course very different in their general style and power characteristics.
I suspect that, as you have been a fan of V8 RWD vehicles, the Evo wouldn't quite cut it. But you would have to decide that for yourself.
I've found that I personally favor RWD V8. I can respect FWD/AWD turbos, and get some giggles out of them, but it just doesn't do it for me, especially for a daily driver.
Just to use an (ancient) example, I found out a long time ago how different they can be. I was car shopping, and one day on the same day, I test drove both a 5.0 Mustang and a Plymouth Laser turbo AWD.
Both cars seemed to have decent performance. The Laser, admittedly, gave me more giggles when the turbo kicked in. My initial impression upon exiting the car was that it was faster. Then, after the initial turbo-high wore off, I realized that both cars actually performed about the same. The Mustang gradually and steadily crept up in speed, due to the larger engine. The turbo Laser was boring..boring...boring..are-we-getting-there-yet...(ssss)..Whee!!
As a result, it was more dramatic, and left the impression it was faster.
Since then, my impression of turbo 4s has usually been about the same. Though, admittedly, I haven't driven/ridden any turbos that are less than 10 years old, and I hear that turbo lag is not as bad as it used to be, so I might just be posting for nothing.
My daily driving consists of lots of intermittent, erratic traffic. I usually woudln't have a good enough run to build up enough boost to get the turbo going. So, a lot of my daily driving would be with just a regular 4cyl econo car, effectively, in a turbo-4. Or, I'll be out on the highway, sandwiched between cars, and an opening suddenly appears to the left that I have to move into quickly. I don't know if I could build up enough boost to get a turbo-4 into the opening. But with a lot of torque, it can be done. (I'm not talking really tight gaps that are unsafe--I won't do that--but ones where you still have to accelerate reasonably quickly or skip the opportunity).
Anyway, I guess I'm just taking the verbose approach to saying "consider what style of driving you do and what matters most to you."
/edit: I think the Evo may have higher insurance/theft rates compared to the GTO, so that may be something you would want to look into, as it is area dependant.
