My sister's using 5 different brands of glass bottles for my nephew (pardon her for being kiasu).. As follows:
1. Life Factory
2. Tommy Tippie
3. Glasslock
4. Nuk
5. Cherub
Based on her experiment for 1 1/2 years, my nephew preferred Glasslock than any other brands and it's more durable (yet to break even my nephew keep dropping and throwing the bottle) and easy to clean (due to wide bottle neck).
FYI, Tommy Tippee is also good, but it's not durable and broke when my nephew threw it. For NUK, my nephew don't like the bottle teats. Life Factory and Cherub have a narrow bottle neck and harder to clean.
So, I'm getting Glasslock for my baby too. Not many places are selling this brand, but I managed to get it from Parkson.

Thanks for your recommendation. I had bought Glasslock at Parkson.
So far so good, except the teat occasionally get shrink inside while feeding. And I need to open the bottle occasionally to stabilize the pressure in allowing the teat goes back to it's normal position.
My wife complain that the glass bottle is heavy..
However, I can feel the solidness when holding the glass bottle
