Super Sprint vs Head Start

Which one is better for R300?
I always loved Head Start, but Super Sprint looks like a better version...it puts you at the head of the race too and it makes you immune to slows, panels, cactuars...etc. and makes weather irrelevant. The only handicap seems to be that this skill is active (pointless) and makes aethers rather useless.
There's something about Super Sprint that also has brought my attention, it bumps your speed to your Maximum Speed, so theorically, you don't even need to max speed as long as your maximum speed breed choco has 4 stars (500), so you can entirely neglect your Max Speed when feeding your choco.

However, I haven't tested this skill enough how much weather is ignored, and if stamina consumption is greater during this super sprint...or any other potential handicap to take into account (SE and hidden passives are good friends).

Anyone who tested this skill can shed some light on the subject?

Nvm super sprint does not ignore cactuars or pannels, just heavy it seems. Think I'm gonna go with head start + choco cure III.
