Bottles...which are the best???...

Vee
Just wondering the opinion of what you think the best bottles are, and why? I am trying to finish my registry and came to this portion and there's so many to pick from, Tommee Tippee, Dr. Brown, Phillips AVENT, Thermos, Medela, etc....I would like to know which specific ones from each brand, cause there's more to choose from once you narrow down to a brand...
