With the quality and performance of an automatic today; especially the 7AT in the 370, if I was getting a car for and/or that would be used as a daily driver there would be no choice for me; it would be the auto.
As with most things in life, once you've had many vehicles with manual transmissions the "uniqueness" wears off and you are left with a choice based on more practical matters than how "connected" you feel to the vehicle or how much "control" (real or imagined) over the driving experience...spend a couple of hours a day in stop and go traffic; especially if you live in a area with lots of elevation changes and the benefits of an auto in a daily driver become very apparent.
I've enjoyed my 7AT...I love the manual mode and the paddle shifters and equally love being able to let the transmission do all the gear changing when I don't feel like doing them)...when doing the Dragon as I do fairly regularly I don't feel as if I'm giving up anything to any other car, including other 370s just because I have an AT and they have the MT.
That said, I will be ordering my replacement for my current 370 soon and I'm seriously considering getting the 6MT this time mostly so that I can live with the rev-match feature (it won't be a daily driver).
In the '50 and perhaps up through the mid-'90s or so the performance of a manual driven by a very good driver were quite tangible but in today's world, it really and truly comes down to personal preference.
Get what you want for your own reasons and you'll be happy with your 370 (and after all, isn't that what really matters?).
