Partial can be hard to understand and do right. But studies show partial is done more than full. With partial it is easier to back out. But if you get partial hanging right, unlike full suspension, you can still breath and you will not feel suffocated until unconsciousness. Unlike full suspension, Your ligature material and anchor point doesn't necessary need to be as strong since they only need to support your partial weight.
If you can find a high enough and strong enough anchor point to do full suspension from, it's a certain thing. Once you kick that chair, there is no backing out. You will obviously feel the pressure from your full body weight and you will suffocate but it's for a few seconds until unconsciousness.
