I know this has been answered by purchase of a Titan.

I have a now very old Bosch 12V drill. And it has been absolutely fine in terms of power.

But if buying a drill today, I wouldn't be very tempted by a 14.4 V cordless. I think I'd either go for a very cheap one such as Aldi/Lidl. Or a decent 18V one. Or live with a mains drill.

(I do now have an 18V Makita so the choice would be "Which model Makita?" - but if you haven't got one, it is a high cost of entry.)
