I have the same Macbook as you the mid 2010 model and it runs Mavericks flawlessly. It seems more responsive than Lion 10.7 and is well worth upgrading as the battery life improves slightly too. I got 4 hours out of my MacBooks battery in Lion, but under mavericks i get at least 5.5 hours on a full charge with the original battery.
Mavericks runs fine on my unibody late-2009 white. However, I upgraded to 8GB ram and a SSD when still in Snow Leopard (both aren't really necessary). Comparing to Snow Leopard, Mavericks provides better battery life. If you're a developer or have a Crossover license, check if you have licenses that support 10.9. For example, nVidia CUDA drivers doesn't work with 9400m + Mavericks.
2GB of RAM is the bare minimum Mavericks will install under. That is really cutting it close especially on any OS after Snow Leopard! Right now I am using 2.71 GB of RAM out of 16 GB just having Google Chrome and Spotify open under 10.7.5. RAM usage in Mavericks is slightly better however.
