Around here we have the option to do either, I prefer the EJ due a combination of factors, namely I'm more comfortable with it, no risk of equipment failure, and the flow rate. Most literature agrees that with a humeral head IO meds will reach central circulation in about 1 second, slightly longer with a tibial. Generally the flow rate is equivalent to that pushed through a 21-gauge catheter. Sternal I haven't read much on, but man it looks cool 
I always look for a peripheral first, easier to secure and for all the reasons listed above.
Now, that being said, if I take a glance and don't see a darn thing I'm going straight for my drill rather than dig around in the meat!
