Hmm - IMHO both approaches work.
I tend to favor compressed coils for RDAs, EVODs, protank etc and loose wrapped for genesis style atomizers.
Although I have used loose wrap coils (using a 4-40 screw for uniformity) in all my devices from time to time.
I do in general prefer compressed coils because it is easier to quickly change to fresh wick and they are heartier.
For cloud chasing I really like the simple wrapped coil: 24 gauge, 1/8" drill bit, 4 loose wraps twice on a single wire for dual coil - saw it on youtube(happyvape) - works really well.
