I'm a contractor and I use my cordless tools every day. When not on a job, I'm doing something on the farm, so it's a rare day that I don't use a tool for something. I started out as a big fan of DeWalt, and Milwaukee, but they didn't hold up very well and DeWalt kept changing their batteries. The good thing about DeWalt is that everyone carries them, so you can go to any Ace Hardware out in the country and find DeWalt tools. I still buy them when I'm desperate to do a job and willing to buy anything that's available.
Most of the time I'm on jobs by myself, but sometimes there are other contractors there doing something. Most of them have DeWalt. Easily the most popular brand out there. 100% of the guys that I've let use one of my Makita tools when they had an issue, have commented on how much nicer they are. I also think that you can "feel" the difference when using them.
My Dad is 84 years old and the last couple of years he has lost a lot of strength. He still wants to go out into the woods and cut firewood, but he's just not able to start a chainsaw anymore. So when it's cool enough outside, he takes the Mule out to fallen trees and limbs them for me using a Milwaukee M12 Sawzall that is super lightweight and easy to handle. He has a couple of pruning blades and just the one battery. It lasts as long as he can, and when the battery is dead, he calls it a day.

Makita doesn't make anything lightweight like the M12, which was a big factor in buying it. The battery is a bit challenging for him to get out, but he's figured it out with a pair of channel lock pliers. For his limited use, it's proven to be a very useful tool.
Home Depot sells both Makita and Milwaukee. I would suggest going there and putting hands on both brands.
One thing that I have run into recently is empty shelves for tools. I needed another router for some doors that I was building and my local Home Depot and Lowes where both sold out. Closest Home Depot with one was 100 miles away, and closes Lowes with one was 60 miles away.
