Any major brand is good Milwaukee Dewalt Mikita Bosch metabo
I would highly recommend Dewalt they have been very reliable and have always done the job for me
I finished hooking up my ARO Filter regulator lubricator that I got for Xmas just haven't gotten around to hook it up until now
I also picked up a remote control out so I can remotely turn on the compressor because it's in a different room than the shop I also got a bunch of new tools for my birthday
The battery nailers are a lot more convenient and better in my opinion but they will be a lot more expensive
all the compressors and nailers you are considering will do the job just fine
I've used bostitch nailers and compressors a lot and they have never disappointed me bostitch is really well known for their nailers and almost every pro has one
ive used the porter cable compressor once and it was nice and did the job just fine I've talked to a guy that swears by them
ive never had any experience with the Dewalt nailers or compressor but almost all my tools are Dewalt and from my experience with Dewalt you won't have any problems with them they make good quality tools
dewalt porter cable and bostitch are all owned by the same company Stanley black and decker so my guess is that they are all made some what similarity
