I dont find biotera to have any hold. I dont find the ultra defining gel to be anything like BHRG. It defines like nothing I have tried before but has a light/med hold. Its great for me in the winter when I dont need much hold but come summer I would consider using BRHG over it if needed.
For me it takes a lot of arc angel and my hair feels producty from it to get hold. Check the swap boards someone had the big 33oz for 15.00 for the arc angel.
