Highs are easier to correct, at least for me. In the 54 years I've been a Type 1 I have only been hospitalized ONCE for a high, but have ended up in the ER many more times for lows. After 54 years I have hypoglycemia unawareness and have found the pump and my CGM an absolutely invaluable help in avoiding serious lows.
I recognize the symptoms of highs when I get above about 250--my eyes get "funny" and I start reaching for the water. I feel "different." But by the time I actually feel low (which means I've ignored the warnings from my CGM) I'm usually approaching "critical" stages, and I get the panic that goes along with that.
For me, I'd much rather be high. But as I'm sure you've heard many times before, every diabetic--and every specific case of diabetes--is different. Be comfortable with whatever you decision is if it works for you.
