I have one of each and frankly neither one of them will hold the lid open on a nose high incline, that S spoiler is pretty heavy. I've read all of the horror stories about the struts but haven't had any issues with mine. Both of them work okay on level ground so it's not something that I've had to think much about.
I wonder if you could rig it up to have both struts and springs, since you have the parts. That might work.
