These are all personal decisions. There are people on both sides of the fence.
There is an "automatic versus manual" thread here with many posts. I like the manual but I don't laugh at anyone with an automatic. I used to have a SAAB automatic. In fact, I drive more economically with a manual because I shift up early versus gun the engine with an automatic.
As far as options, I don't like a sunroof. Just another source of a water leak. Some love it, though.
Some say the Arc's 210 hp is mostly good for faster top speed but that 0-60 is hardly faster than the Linear. That's up to you. I like the Linear's manual AC because an ACC can't read my mind as well as my hand/arm can. The Arc has optional bi-xenon lights though a smart guy in Singapore posted how to retrofit a car that doesn't have it. At least one poster didn't like the black lower trim on the Linear. If so, count it as a strike against the Linear.
