Plasma cutter: High Frequency Start vs. Blowback Start

I cant seem to find any articles or videos that can help me decide which type of plasma cutter I want. Can anyone here tell me why I would or wouldn't want high frequency start vs the blowback type? Would one be more dependable? if they were priced the same, which would you want and why?

Thanks in advance!
