Glass is worth trying if you are interested in it. It has no drag so you don't need much lube, and it is very durable and easy to clean. It also retains temperature, which is nice.
I would say it is very different from softer materials like silicone because it allows for hard and direct pressure (like on the g-spot or p-spot). And the hardness of the material makes for different sensations.
But, as Gunsmoke said, no material is better. It is all a matter of preference.
I prefer glass over any material so it is a matter of preference. But glass is hypo-allergenic, latex free, phthalate free, non-porous, and completely body safe. It can be shared between partners because it can be fully sanitized by boiling. You can use glass for temperature play. I even have a couple of glass dildos that are great for body massages.
Plus, it's borosilicate glass so it is HIGHLY unlikely to break with normal care and use so there's no reason to be afraid of glass.
I personally like glass and metal toys over wood and silicone toys simply because they are heavier and unforgiving. I like how heavy they are and make their presence known while applying pressure on various fun spots.
For me, I prefer silicone luxury vibrators, glass and steel dildos. One of these days they'll actually make a good motor in a glass or steel toy and I'd be in heaven!!!
If you've questions or doubts about glass toys, I'd suggest saving your points to get a glass toys and trying it out. You'll never know until you try it!!
