Probably not... the S5 is twice the price, and a marginal power efficiency and speed improvement over the S3. It's essentially two S3s in one body, without the water cooling of the C1, plus a marginal improvement in performance.
And really they just gave people a reason not to buy the C1. They just made their own product obsolete.
The C1 was probably way to much for most people. I have zero interest in taking care of liquid cooling. I am considering the S5.
you probably want to shop around before you commit to that S5... we are moving into a dense time in mining and any rig bought now needs to be super-clockable up and down to stay profitable.
I am only running 1THash/sec. I only mine as a hobby. I have 1 S1 and 2 S3's mining away

Although on the same page the heat the S1 gives off is amazing in these cold months lol, mind you slippers and sweaters are a solid and cheap counter to cold lmao.
