Its between these 2 burners please help me decide

I do extract brewing and the most i would do is a 6 gallon boil so which of these 2 burners would be best for my brewing needs the bayou classic sp10 or the sq14?

My very personal opinion is the sq14. I started out with the sp10 while borrowing it, then bought a sq14 and I like the sq14 better. Felt more sturdy to me. Both worked well though.

Which one could you control the boil better with?

Both are pretty good for that. Never noticed a difference.
