I attended one live CE once and honestly I didn’t absorb the information as well as I would like. I regretted afterwards, since it was unrelated to my field of practice yet I had to put quite an amount of efforts scheduling the time for it. I found that it didn’t help expand my scope of knowledge on the topic as I would attained in a self-study coursework. Normally, I studied/updated certain materials based on my own available timing thus enabled me that flexibility to do more research on it. 

From my own experience, I can conclude that Live CEs are costly, not conducive to my learning objectives, as well as being a time constraint to my already busy schedule.
