I've been through this recently.
For the yard tools, I went with Ego for the mower and blower. No complaints. It doesn't provide the same suction for sucking leaves and mulching as well as a gas mower--but is likely the best 'green' mower out there.
For tools, I just picked up the Milwaukee M18 Fuel, the M12 Ratchet, and the M12 Fuel. Very happy with all three. The M18 1/2" drive loosened my control arms like it was nothing. The Ratchet is great to get into tight places. I recently used it to get my lower shock bolts where the even smaller M12 couldn't fit.
The M12 Fuel is used for almost everything else...compact size and powerful. I tossed my Ryobi in the trailer and only use it now to lower and raise landing gear.
