Well, granted that I put Eberron as my favorite setting, I think it will figure it out the Warforged. I just like Gnomes. They're funny, eccentric, and I can relate to them a lot (I have ADHD and ASD). Lizardfolk are also one of the races that doesn't act like typical people (don't understand typical emotions/laughter, act strangely, etc), so I also relate to them.
Aasimar are cool. I probably prefer them to tieflings, if only because their subrace "nova" ability is always cool. If I could do a top 10, they'd definitely be up there.
