I love both cars but we spoiled ourselves and got the 300. We have the Cuda if we want to cruise in a classic. It's noisy, feels every bump, bad gas mileage, hot (no A/C) but fun and gets lots of comments. Best of both worlds.
Seems kinda silly we enjoy driving a bumpy loud car that never passes a gas station and costs us lots of money. But what the hell I like it.
The 300 for sure is the best riding car Iv'e ever driven, and I don't need to put my hearing aids in to hear the radio.
