I focus on speed first and foremost, reason being that often I’m on an extremely tight schedule and have deadlines for functional prints. Accuracy and versatility come second. Ease of operation is not a concern for me at all given that the problems I encounter don’t actually delay my schedule (e.g. I’m OK with having 6 steps between model and start of printing as long as the print doesn’t fail 3 hours in.)
That’s just me though. I don’t imagine too many others would have the same priorities that I do.
