These days, they will all be great. Like mentioned above, whatever you buy first should be what you stick with. My first couple tools were DeWalt 20V. So therefore everything I own is DeWalt. I have been super happy with mine. I basically did a full remodel with all DeWalt 20V tools. I have the circular saw, drill, impact, reciprocating saw, hammer drill, jigsaw, cutout tool, vacuum, radio, flash light, blower, weed eater, chain saw, pole saw, framing nailer, finish nailer, and grinder(I think that's all). I also bought some 60V batteries that make the tools run longer.
