I recently purchased the 18v set from Home depot. This is for daily use in construction trade. At this time I am happy with the performance of both tools. I am using the smaller 1.5ah batteries, they recharge in 15 minutes. They last 70-80% of my work day which consist of off and on usage,but not a constant (such as drywall install). Its nice to be able to drill pilot hole and then drive in screws w/out having to change bit since having the combo kit.
I tried the Makita 10.8 first very briefly. I bought the 10.8 took it home drove a couple 4" screws and knew it was not enough for work, probably o.k. for home actually probably Great for home use, nice and light. Speaking of light it is a plus that they have led lights on the tools, very helpful. So at this time I do reccomend the makitas for my type of work.
