I would always prefer to do it onsite instead of virtually. You will have better discussions and it is much easier to learn from other students and/or share experiences. You can lookup the location where the course is given and if it is not around the corner then you will have to travel or search for a local partner who has experience to ask them if they can organize something. If you just want to get certified then doing it virtually can help as well of course.

Good luck!!

I prefer online, as I can record the sessions and rewatch them, also travel and accommodations is a lot of time and hassle. 
 

I don’t mind the interactions with others but there is often a downside of people deciding that they want to talk at length about their own problems, or attempting to triage issues during the course.

i find the anonymous nature of online courses discourages that.
