New technology allows higher voltage batteries to be smaller and lighter than the older lower volt ones. A few extra V's are a big help. Batteries for the old tools will be around for a long time so they won't be obsolete.

The 18V batteries do not last long on a charge. The 20V has so much torque, I can hurt myself.
There are zillions of Milwaukee vs DeWalt tests on youtube, I like this one

I guess I am still living in a cave. Two years ago I built a big addition onto my house using my 14 volt DeWalt cordless drill. That thing is a champion! Worked fine, what a great tool.
The 20v are more powerful , stay charged longer. If you have old 18v Stuff there is an adapter to use 20v batteries. I haven’t tried it though. I don’t regret one bit switching to 20v dewalt.

I built a 96' long foundation super insulated solar home in the 80s with a 9.6 Volt Makita.

Amazon sells generic replacement 18v batteries for around $22 per. They are nimh batts and hold more juice than the old nicad batts, are lighter, and will charge on the old style charger. I just bought 3 and so far so good. Dewalt 18v replacements are $100/2. I just saw they do make a 20v lithium ion to 18v converter with charger. I think you need an adaptor for every tool you want to use (I.e. You are limited by the lesser of the number of batteries and adapters you own). Not a big deal, but as a one man shop I would want at least two adapters as I don't want to switch batteries when I switch tools.
I used to own Dewalt cordless tools until they refused a warranty on a defective chuck, I've never bought a Dewalt tool again. I have slowly replaced all the Dewalt tools I had.
