I would definitely recommend OXO over Pyrex or Anchor (or any brand using tempered glass) because they are much less likely to catastrophically fail when exposed to sudden temperature changes. Zwilling also produces borosilicate products as do some smaller brands.

The one benefit of Pyrex's tempered is that they do have a bit more impact resistance than borosilicate, but you sacrifice a HUGE amount of thermal shock resistance for that (and Pyrex's choice to stop using borosilicate is unquestionably one made due to costs.)

The people saying they have had their Pyrex for a gazillion years and they are great...those are borosilicate products from back when Pyrex used borosilicate on the glass they sold to consumers.

How common is it for tempered Pyrex to fail? It's not a common occurrence, but it also isn't a rarity. Further, it has caused some very serious burn injuries and I have personally seen one fail and it is quite violent (admittedly, my fault, but borosilicate almost certainly would not have failed in that situation.)
