HTG vs AgroMax help!

Ok well i have always used agromax 400 watt hps bulbs.

But at 69.95$ in comparison to 24.959(over double the price) for a htg hps bulb.


My questions are...

1.Is there really a difference between exspensive hps bulbs compared to cheaper ones?

2. what should i get?

Definitely get the HTG one. It's like buying Annies instead of Kraft macaroni and cheese
