Has anyone actually noticed a significant difference with Magnesium Glycinate over other cheaper forms?

I've been falling down the rabbit hole of sleep optimization lately, and it seems like every biohacker online swears by Magnesium Glycinate for that elusive deep sleep phase. I used to just grab whatever was on sale at the local pharmacy, which I now realize was mostly Magnesium Oxide—total waste of money for sleep, apparently. So, I bit the bullet and bought a high-quality brand, and honestly, I think I’m sleeping slightly deeper, but maybe that's just the placebo effect talking? My dreams have definitely become way more vivid, almost movie-like, which is a bit intense for a Tuesday night. I’m really curious if others here have made the switch and felt a genuine, measurable improvement, or if we’re all just chasing a supplement ghost. Are you tracking your deep sleep percentages with a wearable to see if it actually does anything, or do you just go by how you feel in the morning? I’d love to hear if anyone found a specific dosage that hits that sweet spot without the morning grogginess.
