I don't think I would be able to determine an absolute best, but there are some notable ones.

My "Red Rider BB gun" when I was little was the Tyco Crash Test Center and one year I actually got it. Another year I got a Sega Genesis. For my 10th birthday I got Sonic & Knuckles which (connected with Sonic 3) became my all time favorite game.

My birthday this year was nice in that I got a Death Star mug from my mom and my girlfriend made me a taco dinosaur blanket.

I have a hard time thinking of good gifts for people. It's nice when I actually think of something that they end up using for a long time. I got my mom a knife set one Christmas that is still in use. As well as a couple frying pans another year. Most gifts I get her I feel fall flat.

I made a charm bracelet for my girlfriend's birthday this year signifying various moments in our relationship. Her birthday the year before when we were still only friends I got her some tiny hands you put on your fingers. Those made her day.
