Would you rather take courses face-to-face or remotely?

It depends what you are trying to accomplish.  Some training is for purely educational reasons, or for certifications.  Then remote training can be more convenient and cost effective.  But if a part of your training is also to create new relationships, build your network, and learn from the experience of your peers then face to face is an important part of that learning.  For example if you're moving into a new industry and looking to also develop some new contacts or if you're moving up in your current role and looking for a mentor.

I prefer remote training, because there are so many additional options if I do not need to take travel into consideration. But it is difficult to ensure people are engaged (not multi tasking) and you can miss out on some of the networking opportunities that in person can provide. 

I prefer face-to-face but enjoy the convenience of remotely in some cases.

I think that face-to-face courses bring added value, however with today's capacities, distance courses also have their share of advantages. I like the hybrid model where there would be the possibility of being able to do both. I nevertheless believe that it is case by case there are lessons which are given very well at a distance and others where the presence offers a better training.

Depends on the type and duration of the courses.
