I would suggest to start out in hyper. The only reason I started out in turbos and regular speeds is because there were no hypers. I think a lot of people can say the same.
It'll be easiest to learn end game concepts and struggle through major leaks when you're risking the smallest amount of money. Also, it's not like a strong end game isn't required to be a good turbo player.
The amount of info available, the speed of the games, the availability of players at any buyin level and the possibility of a high hourly rate make hypers the best game to learn for most, so I would go with them from the start.
Turbos can be good too, especially off Stars, there are some nice soft games and fair rake... but the majority of players should probably focus on hypers (or hypers and turbos) when playing. Going turbos only I'm not a big fan of, unless you've already played another form of poker, deeper stack perhaps, and you want to transition into hypers, turbos can be a stepping stone where your deeper stacked skills make it easier to pick up on 30-50bb play. But you'd still need to focus on short stack play in that scenario too, you just get to 8-30bb too often in a turbo not to need a strong end game to get a big edge.
