Good stuff here so far, I'll just add to do the math to make sure the AF on the Venture is worth a PC.
Basically, if you don't spend $12k or more each year you're better off with a QS after you subtract the Venture's $59 AF. Also keep in mind the Venture "miles" are really just cash back for travel expenses, while the QS rewards are actual 'cash' with no restrictions.
That said, I would recommend to anybody looking for a new Capital One card to give the Venture a good look if they were primarily seeking rewards and didn't need a 0% promo. I got a Venture WEMC a few weeks ago, and before the first AF is due I plan to PC to a QS WEMC to have the best of both worlds.
Just my 2¢.

Thanks for the replays. I'll keep the Quicksilver and apply for the Venture sometime later this year or maybe since I won't product change the Barclay Arrival Plus. Any comments on it?
I've had the Venture card, but never had the Arrival Plus, so I can't say for sure, but IMHO
-its benefits are similar to the Venture
-the starting limits are good but not as good as the Venture
-I'm sure it doesn't have the no-fee or no-interest balance transfer offers which Venture keeps offering
-Barclays is a flighty bank, while Capital One is a straight shooter
-Barclays does give you a once a month view of your FICO 8 Transunion score, while Capital One gives you a weekly look at your less valuable TU Vantage score
-the Venture is one of the nicest cards out there esthetically (if that matters which I guess it doesn't 
)
To me the Venture gets the slight nod.
