Chippewa's are my favorite honestly. http://www.chippewaboots.com/
I wear the Super Loggers nearly every day, have had the same pair for approaching 2.5 years, working in oil almost every day. Best wearing and lasting boots out.
Georgia Boots seem to take a while to break in, first few days is usually pretty painful, but don't take long to soften up.
I have the Wellington steel toes and wear them maybe once or twice a week and love them. A little on the heavy side though.
