Who do you find more difficult

Bots or bugs? Just curious as to what the general consensus is. Also want to know why you think so. I find bugs to be more difficult. Could just be a skill issue but I started on bugs and religiously played them all the way to level 45 mostly on 9-10 difficulty. Then switched over to bots and after about a day of getting a load out locked in found that the ranged battles and seeking cover was an easier play style for me unlike getting swarmed by bugs constantly.
