Theres no pros or cons to either, other than personal preference, there are no studies to show one is better than the other.
Trimming is a pain, and I know as I've done many big plants at one time needing more than one person to get involved. The best advice I can give is to get set up before hand and comfortable. Set up the TV, Ipad or whatever it is you want to watch or listen to. Next thing is positioning as your back will be the first thing to give out, try to sit up right as its easy to slouch down but don't. Use a pillow to support your lower/middle back. Pull off the big fan leaves before getting into trimming. Then begin trimming for 30 minutes or so, then have a little break, have a drink and something to eat and repeat. Theres really no secrets to it just hard work unless you have a bag trimmer or auto trimmer but i prefer to trim by hand. Hope this helps. We all go through it. Also, I find wet trimming easier as the buds are still swelled up. when dry its more hassle to get into.
