Don't go by looks. I prefer the e270 in looks but compared to the 320 it's horse shit IMO. The 320, as ivy said, will give you more power, as well is way more comfortable than the 270. Plus, it's easier to eco-mod the 320, as well the stock audio is much better. Factoring in if you want to add a sub id still go with the 320, 270 rattles like a bitch. That's my preference though.
