I use these. Live in Arizona and most of the ground I camp on is pretty hard. I've bashed them with rocks many times and so far haven't had any failures.
edit: Just noticed that they only seem to have the XL size for sale at that link right now. The ones I got were the regular size.
I’ve had really good luck with these, they are wonderful and are super easy to set up.

I bought the footprint with my tent, used it once, and it's sat in my closet ever since. Might come in handy if you're camping on rocky surfaces where the tent could get damaged, but here in Florida is basically sand/grass and I'm not concerned.
The stakes it comes with are not good, get something skookum like these that will hold the tent in high winds if a storm ever blows through.
I’ve tried a couple of the generic y stakes from Amazon...the “TNH” ones weren’t bad, but they weren’t amazing either. Just straight-sided, cheap aluminum. They held up well enough that I’m about to donate them to a friend’s kids’ scout troop along with all the other stakes that have accumulated over time. I wouldn’t trust them to hold up to being pounded in with a rock or mallet, but they get the job done as long as the terrain isn’t very rocky.

For just $9 (only $5 extra if you choose the minis) more for a six-piece set of Groundhogs, though, I’d pay the extra any day, as long as I had it to spare. The MSR also have three hook notches on the head instead of the single notch you see on a lot of the cheaper ones, and they’re slightly spiraled at the ends to go in easier.
