I've trimmed both ways. Here is a few pros/cons to each way that I've personally experienced.
Cons- Sticky scissors, loss of trichomes, drys faster.
Pros- Scissor/finger hash, more aesthetically pleasing, drys faster (benefit in cold/humid climates), easier to trim (debatable). Loss of flavor due to quicker drying (depending on climate)
Cons- Loss of more trichs compared to wet trimming (drier plant=trichs brake off easier imo), harder to trim due to leaves curled around buds (debatable), higher risk of mould (especially in cold/humid climates).
Pros- Preserves terpenes better, lengthens drying time, protects buds from hair/dust when drying.
Either way is good in my opinion, no right or wrong way to do what we do. There are just different methods
