Well, I'm certainly not going to get into a debate about who makes a better cordless tool. If the tool does the job and keeps doing the job, you have a winner.
I went with Ridgid for one reason, the lifetime service agreement through Home Depot. I've had a lot of battery issues with cordless tools, going back to the 90s with Dewalt nicads to Ryobi lithium. I just could keep a battery for much longer than a year.
I bought my first Ridgid set in 2012 and I am still using the batteries that came with that toolset. So far, the Milwaukee batteries haven't failed with the oldest battery in its 4th year.
May my luck with the current crop of batteries last.
