Ok i have 2 Pioneer TS-W1001C – 10” (400 watts RMS). Amp is a Cadence Z1000.
I was wondering what is the best load to run at want to know some advantages and disadvantages of running at these if anyone can help.

Well through my mindless browsing the web i came across something which pretty much confirmed everything I believed about the difference.

The only thing i want to know now is will my subs hit a lot harder at 2 ohms or 8?

The subs will hit harder, and the amp will run more efficiently (along with producing more power) at 2 ohms.
Less ohms = Less resistance = More power
In case you don't have it, here's a link to your manual. It's all inclusive (covers all the Z series Cadence amps). Your amp's specs are on page 24.
Based on the manual, your amp is 400 x 1 @ 2ohms (the best you're gonna get out of that amp). From what I could find on the subs (TS-W1001C) they are 4ohm SVC's rated at 400RMS 800Peak. You'll only be sending 200 watts max to each sub with that amp, so you're gonna be underpowering them by 200 watts. There's nothing you can do about that unless you get a larger amp.
Wire the subs in parallel (see the diagram below) for a 2ohm load. That's your best possibility with the equipement you listed.
