For the most part they feel the same, although stainless will feel more heavy. You will find more textures in glass than stainless. Stainless will hold temps longer but takes longer to reach said temperature. Lastly, nothing short of a welding torch will harm a stainless toy, dropping it will only break the surface it is dropped on, toes, tile, sink...Well you get the idea.
I would say if you like glass you will also like stainless toys as long as you are not a texture freak.
