My gf wants to get me on for Valentine's day and I'm stuck between a few options. I'd like to go cordless tbh.

So I'm a pro but I currently don't use a sander too too often. I have mostly Milwaukee platform but recently got a bunch of Makita tools as well (w 5x 5mah batteries.) I also have one Dewalt flexvolt grinder and battery.

I'm really trying to decide between the 18v Milwaukee and Makitas. Heck I have heard some good things about the Ryobi orbital sander too. And I recently found out the HF orbital sander can work with my Dewalt battery.

So can anyone give me some personal advice on which ones they prefer using or stories with them?

I'm open to a corded as well if it's above and beyond the others.
Thanks in advance.
